表面催化剂就是只能在表面接触催化的催化剂。 例如工业上SO2氧化SO3就是用接触氧化法氧化的,SO2和O2在V2O5(催化剂)表面发生化学反应。所有的化学反应都在催化剂表面发生,这也叫做界面现象。
多相催化剂先将盐吸附在它的表面并使它固定在那里。
The heterogeneous catalyst first attracts the salt to its surface and holds it there.
作为纯金属时可镀于其它金属表面,也可作催化剂。
As pure metal, it is used to coat other metals (see plating) and as a catalyst.
同时分析了孔隙率和催化剂表面积对催化剂层性能的影响。
The influence of porosity and active catalyst surface area on the performance of cathode is analyzed as well.
