Catalysts based on Zr-O material were prepared from zirconium oxychloride and zirconium oxynitrate with ultrasonication. The deposited Zr-O materials were not detected by XRD because of amorphous phase of an oxygen deficient type zirconia. The obtained zirconia based composite showed higher catalytic performance for oxygen addition activity than Pd based composite for the combustion of carbon. However, the obtained zirconia based composite showed the less catalytic performance for dehydrogenation reaction activity than Pd based composite for the combustion of methane. This zirconia based catalyst is expected to use for the electrode material of the fuel cell that needs restraint of the carbon deposition. (C)2014 The Ceramic Society of Japan. All rights reserved.

記述言語：英語出版者・発行元：日本粘土学会

Intercalation behavior of acetylsalicylic acid (ASA) to interlayer of hydrotalcite (HT) was investigated in various organic solvents to synthesize ASA/HT composite. ASA intercalation to the interlayer of HT did not occur in an aprotic solvent like acetone but occurred in a protic solvent like alcohols. In the case of alcohols used for solvent, the intercalation behavior was revealed to depend on the alcohol's type. In the primary alcohol (methanol, ethanol, 1-propanol, 1-butanol, and i-butanol), the acetylsalicylate ions were not intercalated, but the salicylate ions were intercalated into the interlayer of HT because of the complete decomposition of ASA in the solution. Since ASA decomposed partially in the secondary alcohol (2-propanol and 2-butanol), the both acetylsalicylate and salicylate ions were intercalated into the interlayer of HT. On the other hand, the decomposition of ASA was substantially restricted in the tertiary alcohol (tert-butanol) because of the stability of the tertiary alcohol. As a result, the acetylsalicylate ions were found to intercalate into the interlayer of HT over 80 mol% and ASA/HT composite was successfully obtained using tert-butanol as solvent.

The purpose of this study is to clarify the physicochemical properties of Ti2O3 for hydrogen production. The hydrogen production properties of Ti2O3 before and after milling in pure water were investigated in a flat-bottomed reaction vessel made of a Pyrex glass cell which was attached to a closed-gas circulation system under an Ar atmosphere at room temperature using three different types of stirring rod. Ti2O3 was found to be a new material for mechano-chemical hydrogen production, although it did not exhibit photocatalysis or mechano-catalysis for hydrogen production.

Nickel (Ni) nanoparticles were synthesized in micropores of zeolite by the adsorption and decomposition of a sublimated Ni organometallic compound, Ni(C5H5)(2), to invent metallic catalysts with nanosize, which are smaller than 5 nm and keep the nanosize at high temperature. In the decomposition process, Ni species were partially decomposed by ultraviolet light irradiation and fixed in zeolite pores prior to thermal reduction under H-2 flow. Note that the Ni nanoparticles showed an excellent thermal stability, because they kept the high dispersion with diameters smaller than 5 nm even after heating at 400 degrees C. On the other hand, the Ni particles supported on zeolite by a conventional method, which is an incipient wetness impregnation process, became larger than 10 nm after heating at the same temperature. The synthesized Ni nanoparticles acted as a metallic catalyst because they showed higher selectivity for H-2 generation than C2H4 generation during ethanol steam reforming reaction.

記述言語：英語掲載種別：研究論文（学術雑誌）出版者・発行元：AMER CHEMICAL SOC

The photoinduced wettabilities of water, n-hexadecane, dodecane, and n-heptane on a flat TiO2 surface prepared by a sol gel method-based coating were investigated. An amphiphilic surface produced by UV irradiation exhibited underwater superoleophobicity with an extremely high static oil contact angle (CA) of over 160 degrees. The TiO2 surface almost completely repelled the oil droplet in water. A robust TiO2 surface with no fragile nanomicrostructure was fabricated on a Ti mesh with a pore size of approximately 150 mu m. The fabricated mesh was found to be applicable as an oil/water separation filter.

Bioinspired self-cleaning surfaces with superhydrophobicity, superoleophobicity, and superhydrophilicity 査読

Shunsuke Nishimoto, Bharat Bhushan

RSC Advances 3 ( 3 ) 671 - 690 2013年1月

記述言語：英語

Self-cleaning methods currently employed are based on understanding of the functions, structures, and principles of various objects found in living nature. Three types of surfaces, including superhydrophobic, superoleophobic, and superhydrophilic, offer solutions to keep a surface clean. In this review article, an overview of self-cleaning surfaces inspired by nine biological objects is provided: lotus leaves, rice leaves, cicada wings, butterfly wings, snail shell, fish scale, shark skin, pitcher plant, and photosynthesis. These surfaces exhibit special properties such as low adhesion, low drag, anisotropic wetting, anti-reflection, directional adhesion, anti-fouling, photocatalysis, self-sterilizing, and anti-fogging. We discuss the differences between the superhydrophobic and superhydrophilic surfaces and perspectives for self-cleaning surfaces in the future. © 2013 The Royal Society of Chemistry.

K2NiF4-type Pr2NiO4 doped with Cu, Cu-Ga, or Co (Pr2Ni0.9Cu0.1O4, Pr2Ni0.75Cu0.25O4, Pr1.91Ni0.71Cu0.24Ga0.05O4, or Pr2Ni0.9Co0.1O4) were synthesized by a solid-state reaction for use as cathodes in an intermediate-temperature (500-700 degrees C) solid oxide fuel cell (IT-SOFC). Pr2NiO4, Pr2Ni0.9Cu0.1O4, Pr2Ni0.75Cu0.25O4, Pr1.91Ni0.71Cu0.24Ga0.05O4 and Pr2Ni0.9Cu0.1O4 crystallize in the space group Bmab. Single test cells with samarium oxide doped ceria (SDC) as the electrolyte, Ni-SDC cermet as the anode, and the above-mentioned cathode material were fabricated for cell performance measurements at 700 degrees C. Current interruption measurements and electrochemical impedance spectroscopic analysis revealed that the cathode properties of Pr2NiO4, Pr2Ni0.9Cu0.1O4, Pr2Ni0.75Cu0.25O4, and Pr1.91Ni0.71Cu0.24Ga0.05O4 were comparable to that of La0.6Sr0.4Co0.2Fe0.8O3 (LSCF) and the cathode properties of Pr2NiO4 were improved by doping with Cu or Cu-Ga at the Ni site of Pr2NiO4.

The effect of the basicity of zeolite as a metallic catalyst substrate on ethanol steam reforming reaction was investigated. Catalysts with various basicities were prepared using an ion exchange process with aqueous solutions including Na+, K+ and Cs+ after an impregnation process of Ni on Na-Y zeolite (referred to as Ni/Na-Y, Ni/K-Y and Ni/Cs-Y, respectively). Infrared spectroscopy indicated that the OH bonds of ethanol molecules adsorbed on zeolites were weakened with increasing zeolite basicity. H-2 production at 300 degrees C increased in the order of Ni/Cs-Y > Ni/K-Y > Ni/Na-Y, and selectivity for a high production ratio of H-2 to C2H4 was significantly promoted by exchanging Na+ for K+ or Cs+. H-2 production at 500 degrees C was also enhanced by the zeolite basicity; however, degradation of catalytic activity was mainly caused by carbon deposition on the three samples at this temperature. Ni/Cs-Y, with higher H-2 production than Ni/Na-Y, also exhibited higher resistance to carbon deposition. Increase of the zeolite basicity was effective for selective acceleration of the dehydrogenation reaction with ethanol, inhibition of coke deposition, and the promotion of H-2 production.

The aim of this study is to develop a highly efficient and environmentally friendly water treatment technique. Water treatment by photocatalytic zonation over bare WO3 under visible light irradiation (O-3/vis/WO3) system was performed under different experimental conditions using a phenol aqueous solution as model wastewater. The effects of parameters such as the initial phenol concentration, water temperature, and initial solution pH on the total organic carbon (TOC) removal efficiency in the O-3/vis/WO3 system were investigated. The results suggest that the TOC removal process consists of three stages, and the combined effect of photocatalysis and ozonation, which is important for complete TOC removal, became dominant in the third stage. Furthermore, the TOC removal efficiency increased with increasing water temperature in the O-3/vis/WO3 system. (C) 2011 The Ceramic Society of Japan. All rights reserved.

W-doped TiO2 nanofibers with various compositions (W/Ti: 2-8%) were fabricated by the electrospinning method from respective precursor solutions containing tungsten(V) pentaethoxide, titanium tetraisopropoxide (TTIP), and polyvinylpyrrolidone (PVP), followed with calcination at 550 degrees C. Morphological and structural characteristics of these nanofibers were studied with SEM, XRD and XPS. W-doping inhibited the crystal growth and anatase-to-rutile transformation of TiO2 nanofibers. W-doped TiO2 nanofiber mats showed good photocatalytic oxidation abilities for acetone. Obvious color change from white to blue of mats during the photocatalysis process can be detected by naked eyes, which provides a good way in detection of pollutants in indoor air, especially for the volatile organic compounds (VOCs).

LiBiO(3), NaBiO(3), MgBi(2)O(6), KBiO(3), ZnBi(2)O(6), SrBi(2)O(6), AgBiO(3), BaBi(2)O(6) and PbBi(2)O(6) were synthesized by various processes such as hydrothermal treatment, heating and so on. These materials were examined for their photocatalytic activities in the decolorization of methylene blue and decomposition of phenol under visible light irradiation. For methylene blue decolorization, the presence of KBiO(3) resulted in complete decoloration within 5 min. For phenol decomposition, NaBiO(3) showed the highest activity, while LiBiO(3), SrBi(2)O(6) and BaBi(2)O(6) possessed almost comparable decomposition rates. Their decomposition rates were apparently higher than that by anatase (P25) under UV irradiation. (C) 2011 Elsevier Inc. All rights reserved.

The temperature dependence of the hydrogen adsorption properties of nickel-doped mesoporous silica (MCM-41) synthesized by a direct hydrothermal method was investigated by measuring the amount of hydrogen adsorbed at pressures up to 100 kPa at 298, 373, and 473 K. Nickel-doped MCM-41 adsorbed more hydrogen than undoped MCM-41 and metallic nickel at approximate to 298/0, 373/0, and 473 K/0 kPa due to chemical adsorption enhanced by the highly dispersed nickel particles. Chemical adsorption increased with increasing nickel content and adsorption temperature, suggesting the presence of adsorption sites. The nickel doping also brought the spillover effect, which enhances the physical adsorption of hydrogen. The spillover effect was enhanced at high nickel contents and adsorption temperatures.

A series of K2NiF4-type compounds, La2-xPrxNiO4 (x = 0, 0.6, 1.0, 1.4, and 2.0), were synthesized by solid state reaction for use as cathodes in an intermediate-temperature (500-700 degrees C) solid oxide fuel cell (IT-SOFC). La(2-x)Pr(x)Nia(4) (x = 0 and 0.6) crystallize in the Fmmm space group, while La2-xPrxNiO4 (x = 1.0, 1.4, and 2.0) belong to the Bmab space group. The electrical conductivity increased by Pr doping and La2-xPrxNiO4 (x = 0.6, 1.0, and 1.4) exhibited electrical conductivities similar to one another while Pr2NiO4 had the highest. Single test-cells consisting of samarium oxide doped ceria (SDC) as an electrolyte, Ni-SDC cermet as an anode and La2-xPrxNiO4 as a cathode, were fabricated for measurements of cell performance at 500-700 degrees C. Current interruption measurements revealed that the overpotential losses mainly decreased with increasing Pr content. Pr2NiO4 was found to exhibit the best cathode characteristics; maximum lest-cell power densities of 14.1, 45.1, and 104.4 mW/cm(2) were obtained at 500, 600, and 700 degrees C, respectively.

記述言語：英語掲載種別：研究論文（学術雑誌）出版者・発行元：ELSEVIER SCIENCE BV

Photocatalytic water treatment over bare WO3 under visible light irradiation combined with ozonation (O-3/vis/WO3) was investigated using an aqueous phenol solution as model wastewater. The O-3/vis/WO3 treatment exhibited a much higher total organic carbon removal than ozonation alone. Bare WO3 was found to function as an active visible-light-responsive photocatalyst for decomposition of organic compounds in the presence of ozone, which readily reacts with photoexcited electrons in the conduction band of WO3.
