Working mechanisms for the functional surfaces of multicomponent metal oxide catalysts have been extensively investigated for two years. The main results obtained are as follows :The working mechanism of multicomponent bismuth molybdate catalysts has been elucidated on the basis of 180 tracer experiments. A functional model involving the bulk migration of the lattice oxide ion was newly presented. (Moro-oka)The working mechanism of multicomponent bismuth molybdate catalysts has been elucidated on the basis of ^<18>O tracer experiments. A functional model inveloving the bulk migration of the lattice oxide ion was newly presented. (Moro-oka) A novel catalytic process for the decomposition of nitrogen oxides has been developed and the reaction mechanism has been investigated (Iwamoto and Inui). The surface structure of V_2O_5 catalyst for the selective oxidation of n-butane to maleic anhydride has been characterized (Yoshida and Yamazoe). Interactions of nitrogen and hydrogen with Ru cata … More lyst surface and their adsorbed states were determined by IR spectroscopy (Aika). A novel gas sencer for combustible gases has been developed by the functionalization of SnO_2 semiconductor (Yamazoe). Regioselective oxidation of alcohols has been established by using shape-selective catalysis of titanosilicate (Tatsumi). Various catalytic behaviors of heteropoly-compounds have been investigated and a number of new oxidation and acid-base catalysis were developed (Misono). Direct oxidation of benzene to phenol with molecular oxygen has been developed by the combination of the oxygen-hydrogen fuel cell and electrode catalysis (Otsuka). A functionalized membrane for oxygen gas has been successfully applied to the selective oxidative coupling of methane to form C_2 hydrocarbons (Fujimoto). The catalytic efficiency of the photo-decomposition of water has been remarkably enhanced by the discovery of new complex catalysts having layered structure (Domen). Photo-catalytic behavior of copper catalysts supported on zeolites and their interactions with nitrogen oxides have been precisely investigated (Anpo).As mentioned above, catalytic applications of multicomponent metal oxides and their principles have been successfully investigated.
