Novel Environmental Catalysts for Practical Applications.

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 deNOx systems have confirmed the two-stage oxidation of Cu+ions to Cu I D 22+I D 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 I D22文件D2 and the reduction catalyst of NOx has been evidenced to be very useful to increase the effectiveness of the reductant.
