【Abstract】 This review describes in some detail several newly developed in situ technipues for studying the mechanism of catalytic processes and catalyst microstructures with the emphasis placed on the in situ IR spectroscope. A survey is first presented of the features and recent achievements of these techniques. Then some ideas of how to use them in mechanistic study of catalytic reaction and chemical trapping method arc introduced. Finally the characteristics and the applications of a new delicate pulse in situ technique are discussed.更多还原
