Eley-Rideal机理In this mechanism, proposed in 1938 by D. D. Eley and E. K. Rideal, only one of the molecules adsorbs and the other one reacts with it directly from the gas phase, without adsorbing:A(g) + S(s) =AS(s)AS(s) + B(g) Products也就是A物质(气态)和B物质(也是气态)反应,用S物质(固态)做催化剂,机理是A物质先被吸附在S物质上,然后形成一种类似配合物的结构,然后B物质在和这种中间体反应,从而得到产物的机理
