The role of chemical kinetics in defining the requirements for the active sites of heterogeneous catalysts is discussed. A personal view is presented, with specific examples from our laboratory to illustrate the role of the chemical composition, structure, and electronic properties of specific surface sites in determining reaction activity and selectivity. Manipulation of catalytic behavior via the addition of chemical modifiers and by tuning of the reaction conditions is also introduced.
讨论了化学动力学在确定多相催化剂活性位点要求方面的作用。本文提出了个人观点,并结合我们实验室的具体例子来说明特定表面位点的化学成分、结构和电子性质在决定反应活性和选择性方面的作用。还介绍了通过添加化学改性剂和调节反应条件来控制催化行为的方法。
