一般认为催化反应过程是通过反应物吸附在表面上,被吸附分子或者同另一被吸附分子反应,或者与另一气相分子反应,生成的产物最后脱附,使表面再生而进行的。过去,对大多数催化反应机理的研究和控制是通过经验方法进行,亦即从对反应物和产物的动力学观察推论表面中间物,并以此阐明 Generally believed that the catalytic reaction process is adsorbed on the surface through the reactants, the adsorbed molecules or adsorbed molecules with another reaction, or with another gas phase molecules, the final product of the desorption, the surface regeneration carried out. In the past, research and control of most of the catalytic reactions has been conducted empirically, ie, deducing surface intermediates from kinetic observations of reactants and products
