Research Abstract |
Metal oxides based on tetrahedra condensation have provided a variety of porous crystalline materials. The present researches focused on new octahedral metal oxide synthesis with micropores, their materials chemistry, and catalytic functions. Based on the successful synthesis of microporous crystalline Mo-V-O materials using unit-synthesis method, the method was applied to the synthesis of complex oxides with group 5(V, Nb, Ta) and 6(Mo,W) elements. Microporous complex oxides with a similar but ill-ordered structure to that of Mo-V-O were synthesized and showed solid-acid property, particularly to the system with water, and photocatalytic property as well. More research on the Mo-V-O materials in terms of micropore function revealed that the size of the micropore decreased by material reduction due to the enlargement of metal-oxygen bond and catalytic oxidation activity changed with a maximum, which implies that a micropore with a size to reactant alkane can effectively promotes the reaction.
