摘要
Abstract
Three common preparation methods of CuY zeolites were introduced. Although, relative to the impregnation method, the solution ion exchange and solid-state ion exchange methods had lower copper loading, they could make copper component distribute more evenly in the channel structure of the zeolites and had smaller damage to the structure of Y zeolite. The local environment of copper ions in Y zeolites was the key factor to determine the active centers, and it could be effectively monitored by means of IR and H2-TPR. The introduction of the cations promoted Cu to locate in the supercage of zeolite. The recent researches on the catalytic behavior of CuY zeolites for gas phase oxidative carbonylation of methanol were also summarized.关键词
