| Research Abstract |
The successful results have been obtained in the following five groups.
(A01) The Purpose of A01 group was to design active centers for the unique reaction field at atomic/molecular levels, taking into account the clear descriptions of the active centers and actual conditions of environmental catalysis. Successful achievements have been obtained in (1) the fields of heteropolyacids catalysts for molecular design and the application, (2) surface science and theoretical chemistry as tools for catalyst design and (3) model reactions for the proposal of unique reaction fields and the indentification.
(A02) Catalytic chemistry in multifunctional reaction fields was investigated on the purpose of designing the catalyst which can function in the critical conditions as environmental catalysts should work. Success in improvement of catalytic performance has been obtained by (1) combination with multicatalytic (chemical) functions, (2) utilization of photo-and electo-functions, (3) intoroduction o

(A03) Zeolites and mesoporous materials are main topics. As for zeolites, studies covers the synthesis of large crystals, surface structures, dynamics of protons, base-catalyzed reactions, methanol-to-ethylene reaction, and ammoximation. New organic zeolites were also synthesized. As for microporous materials, were studied new synthetic strategies, accurate cotrol of the pore sizes, trimethylsililation and catalic reactions.
(A04) The project of A04 group aims at examining dynamics of molecules in the unique and extreme reaction fields in collaboration with about 20 researchers in catalytic chemistry, chemical reaction engineering, computer chemistry and so on. Some important results were obtained to construct new concept for the design of next-generation catalysts and to establish a new field of "molecular reaction engineering".
(A05) In the research group for hydrodesulfurization, it has been found that a mixture of metal oxide and zeolite was active for the reaction and the active site in Co-Mo catalysts is the Co ion interacted with Mo ions. The researchers for de NOx systems have confirmed the two-stage oxidation of Cu^+ ions to Cu_<2+> ions depending on the reaction temperature and the degree of ion exchange. The new method in which a reductant is introduced between the oxidation catalyst of NO to NO_2 and the reduction catalyst of NOx has been evidenced to be very useful to increase the effectiveness of the reductant.
