Abstract

Toluene is one of the volatile organic compounds that are harmful to the environment and human health. One promising approach for eliminating toluene is catalytic combustion. Although precious metal-based catalysts are known to show high activity for toluene combustion, the high price of precious metals has restricted their widespread applications. In this study, precious metal-free catalysts of Co3O4/ZrSn1−xFexO4−δ were synthesized for toluene combustion. Here, scrutinyite-type ZrSnO4 was focused as a promoter, which can supply active oxygen species from inside the lattice toward the Co3O4 activator. In addition, Fe2+/3+ ions were introduced into the ZrSnO4 lattice to enhance the oxygen supply ability considering the improvement of redox properties and the formation of oxygen vacancies for a smooth oxide ion migration. The oxygen supply from the ZrSn1−xFexO4−δ lattice facilitated toluene oxidation on Co3O4, and the highest catalytic activity was obtained for the 19 wt.% Co3O4/ZrSn0.93Fe0.07O4−δ (Co3O4/ZSF0.07) catalyst, wherein the complete combustion was realized at a temperature as low as 250 °C. The toluene combustion reaction over Co3O4/ZSF0.07 was considered to proceed along a typical route of the rapid transformation of toluene into the intermediates (benzyl alcohol, benzaldehyde, benzoate, and maleic anhydride) and, finally, to the formation of carbon dioxide and water.

Novel catalysts of Rh/ZrSnO4 were synthesized, and their catalytic activities for the direct decomposition of nitrous oxide (N2O) were investigated. ZrSnO4 with an [Formula: see text]-PbO2-type structure was used as a promoter, since the oxygen supply from its lattice was expected to facilitate N2O decomposition. Among the prepared catalysts, 1.0 wt.% Rh/ZrSnO4 exhibited the highest catalytic activity: N2O was completely decomposed at 450[Formula: see text]C. This activity was higher than those for 1.0 wt.% Rh/ZrO2 and 1.0 wt.% Rh/SnO2, indicating that the ZrSnO4solid promoted N2O decomposition. In addition, the 1.0 wt.% Rh/ZrSnO4 catalyst featured high durability in the presence of O2, CO2, and H2O vapors.

Novel Pt/ZrSn[Formula: see text]Sr[Formula: see text]O[Formula: see text]/SBA-16 (SBA-16: Santa Barbara Amorphous No. 16) catalysts were developed for liquid-phase phenol oxidation. As the promoter to accelerate phenol oxidation on Pt, a ZrSnO4 solid with an [Formula: see text]-PbO2-type structure was chosen because its interstitial open spaces are expected to facilitate phenol adsorption. Additionally, the redox reaction of Sn[Formula: see text] provides oxygen release and storage abilities, and the introduction of low-valent Sr[Formula: see text] ions into the ZrSnO4 lattice improves oxide ion migration via the generation of oxygen vacancies in the lattice structure.

Pt/CeO2-ZrO2-Bi2O3-PbO/SBA-16 (SBA-16: Santa Barbara Amorphous No. 16) catalysts were synthesized to produce hydroxypyruvic acid by glycerol oxidation. In the catalysts, the introduction of PbO into CeO2-ZrO2-Bi2O3 improved the oxygen release and storage abilities owing to the synergistic redox reaction of Pb2+/4+ and Ce3+/4+, which facilitated the oxidation ability of Pt. In addition, the oxidation of the secondary OH group in glycerol might be accelerated by the geometric effects of glycerol, Pt, and Bi3+ or Pb2+/4+. Furthermore, the moderate reaction conditions such as room temperature and open-air atmosphere enabled the suppression of further oxidation of hydroxypyruvic acid. The highest catalytic activity was obtained for 7 wt% Pt/16 wt% Ce0.60Zr0.15Bi0.20Pb0.05O2−δ/SBA-16, which provided a hydroxypyruvic acid yield maximum of 24.6%, after the reaction for 6 h at 30 °C in atmospheric air.

CeO2-ZrO2-Bi2O3 yellow pigments were prepared by a citrate complex method and their color properties were characterized to evaluate their suitability as environmentally friendly inorganic pigments. CeO2-ZrO2-Bi2O3 yellow pigments strongly absorb visible light at wavelengths below 500 nm and consequently they are brilliant yellow in color. The most vivid yellow was obtained for Ce0.43Zr0.37Bi0.20O1.90, which had a yellowness value (b*) in the CIE L*a*b* system comparable to that of the commercially available praseodymium yellow pigment (ZrSiO4:Pr). The Ce0.43Zr0.37Bi0.20O1.90 pigment was used in paints for porcelain. We found that the medium yellow pigment (chuuki), which is one of the traditional colors of Arita ware but which contains lead and antimony, could be faithfully replicated without using these toxic elements.

Language：Japanese

Novel PdO/La10Si6-xCoxO27-delta/gamma-Al2O3 catalysts with applications to methane combustion were developed. These materials were based on the use of La10Si6-xCoxO27-delta as a promoter because this compound has an oxide-ion conducting apatite-type structure that allows the smooth migration of active oxygen to the PdO activator. Co3+/2+ ions were also introduced into the original La10Si6O27 lattice to enhance its redox properties. Temperature-programmed reduction measurements revealed that the oxygen supply was facilitated by introducing Co3+/2+, where the reduction was observed at 290 degrees C for La10Si6-xCoxO27-delta (x = 1.0), whereas no reduction was observed below 460 degrees C for La10Si6O27. Among the samples synthesized in this work, PdO/La10Si6-xCoxO27-delta/gamma-Al2O3 (x = 1.0) exhibited the highest catal degrees C required when employing PdO/La10Si6O27/gamma-Al2O3.

Event date： 2015.11

Language：English

A Pt/CeO2-ZrO2-SnO2/SBA-16 (SBA-16: Santa Barbara Amorphous No. 16) catalyst was developed for the efficient removal of 1,4-dioxane. Because the catalyst showed synergistic action between the high catalytic activity of Pt and the high oxygen release and storage abilities of CeO2-ZrO2-SnO2, high catalytic efficiency in the liquid phase was obtained in an air atmosphere without the supply of any strongly oxidizing additives or photoirradiation. After reaction at 80 degrees C for 4 h, the residual percentage of 1,4-dioxane reached 31%. Furthermore, the Pt/CeO2-ZrO2-SnO2/SBA-16 catalyst exhibited high reusability and durability and the rate of net decrease in 1,4-dioxane reached 44% at 80 degrees C.

Novel oxidation catalysts were prepared by artificial control of oxide ion and electron migration property in the solid. Smooth oxide ion conduction and the high redox property increased the oxygen release and storage abilities, which facilitated the catalytic oxidation. Oxide ion conducting property was controlled by selecting the crystal structure suitable for oxide ion migration and introducing oxide ion vacancies in the lattice. Electron conductivity (redox property) was provided by doping ions which can change their valence state. As results, the Pt/La10Si5CoO27-δ/γ-Al2O3 catalyst can completely oxidize toluene in gas-phase at 120℃, and the Pt/CeO2-ZrO2-SnO2/ZrO2/SBA-16 catalyst can completely remove phenol in liquid-phase under the moderate conditions at 80℃ under the atmospheric open-air system. Furthermore, glycerol can be oxidized to value-added compounds by using the CeO2-ZrO2-based systems.

In order to effectively remove nitrous oxide (N2O) which causes the global warming and the ozone layer depletion, I developed the novel catalysts for the direct N2O decomposition. I focused on Yb2O3 with the cubic C-type rare earth sesquioxide structure, which has the large open spaces in the lattice. In addition, Co2+/3+ or Cu+/2+ was introduced into the lattice to accelerate the decomposition reaction by supplying the lattice oxygen. As results, (Yb0.85Cu0.15)2O3-δshowed the highest activity, and decomposed N2O at the temperature as low as 400℃. Furthermore, I also demonstrated that the open space in the C-type structure worked as the N2O adsorption sites and the catalytic active sites.

From the viewpoint of the oxide ion conduction in solids, I synthesized novel environmental catalysts. For the CeO2-ZrO2 solid, the Ce4+ and Zr4+ sites were replaced by lower-valence Fe2+/3+, Ni2+/3+, or Bi3+ to increase the oxide ion conductivity caused by the formation of oxygen vacancies. By using these samples as promoters with Pd or Pt, I prepared the novel catalysts, which can completely oxidize methane at 280 degree C, toluene at 100 degree C, and formaldehyde at 20 degree C. In addition, I also demonstrated that the oxide ion conducting solid with apatite-type structure (La10Si6O27) worked as promoters for methane or VOCs oxidation.

In this study, we have developed the divalent cation conducting solid electrolytes, (Hf1-xMx)4/(4-x)Nb(PO4)3 (M = divalent cations), showing high ion conductivity by strictly selecting the well-ordered three-dimensional network structure of NASICON type structure. As the conducting cation species (M), we focused on Mg2+ and Ca2+ and Zn2+, which have relatively small ionic size and low electronegativity among the divalent cations that should realize smooth ion migration even in rigid crystal lattice. All the solid electrolytes developed showed extraordinary high divalent M2+ ion conductivity compared with those for the solids which have been reported, and their ion conducting properties were clearly demonstrated by the dc and ac conductivity measurement in various atmosphere whose oxygen partial pressure is widely varied, and dc electrolysis method. Furthermore, the quantitative M2+ migration in each solid has also been demonstrated by modified Tubandt electrolysis method.
