“中庸”是传统的中国智慧，由孔子提出，不断被他的追随者丰富. “中庸”追求在各种矛盾中寻求平衡，并认为“过分”和“不及”都是不好的. 对于一个成功的催化剂，反应物的吸附，既不能太强，也不能太弱. 在这一点上，“催化”与“中庸”有极为相似之处. 本文以孔子与他的学生对话开始，先讲了3个 著名的“中庸”老故事，结合3个有“中庸”味道的“催化”案例，最后得出：好的“催化”，即是具有“中庸”味道的“催化”.

“Zhong Yong” represents a traditional Chinese wisdom, which was first proposed by Confucius and continuously richened by his followers. “Zhong Yong” pursues the balances among all kinds of contradictions, and insists that neither “too much” nor “not enough” is good. For a successful catalyst, on which the adsorption of reactants must be not so strong and not so weak either. On this point of view, there are the same pursuits for “Zhong Yong” and catalysis. In this paper, the author starts his story with a conversation between Confucius and his student, followed by 3 interesting stories happening in the ancient China, and then 3 examples in catalysis. In comparison with these stories and examples we can conclude that “Zhong Yong” and catalysis do share some common aesthetic standard. Doing catalysis with a taste of “Zhong Yong” must be very interesting and wonderful.
