易错句子We need a catalysis for this reaction.
正确表达We need catalysis for this reaction.
catalysis 通常为不可数名词，在一般用法中不加不定冠词 a，也不用复数形式。应直接使用 catalysis 表示催化作用。
grammar · medium
易错句子The catalyst catalysis the reaction.
正确表达The catalyst catalyzes the reaction.
catalysis 是名词，不能用作动词。表示‘催化’的动词形式是 catalyze。此处应用动词 catalyzes。
catalyst指具体物质，catalysis指过程或作用
catalyze是动词，catalysis是名词
