Heterogeneous photocatalysis and electrocatalysis have attracted tremendous interest in energy chemistry including CO₂ reduction, N₂ fixation, water oxidation, oxygen reduction, organic transformations, etc. The molecular-level understanding of reaction mechanisms in photocatalysis and electrocatalysis is pivotal to facilitate these processes, and the quantitative isotope measurement provides such a toolbox. Herein, we summarize the theory of two kinds of important isotope measurements (i.e., kinetic isotope effect and isotope labeling methods) and then review their important applications in photocatalytic/electrocatalytic CO₂ reduction, N₂ fixation, water oxidation, oxygen reduction and organic transformations on heterogeneous catalysts. Future prospects for quantitative isotope measurements are also presented.

非均相光催化和电催化中的定量同位素测量

非均相光催化和电催化在能源化学中引起了极大的兴趣，包括CO ₂还原，N ₂固定，水氧化，氧还原，有机转化等。对光催化和电催化反应机理的分子水平的理解对于促进这些过程至关重要，同位素定量测量提供了这样的工具箱。在这里，我们总结了两种重要的同位素测量的理论（即动态同位素效应和同位素标记方法），然后回顾了它们在光催化/电催化CO ₂还原，N _2中的重要应用。固定，水氧化，氧还原和非均相催化剂上的有机转化。还介绍了定量同位素测量的未来前景。
