With the intensification of energy crisis and environmental pollution, photocatalysis and

photoelectrocatalysis, as important technologies for sustainable energy conversion, have

attracted widespread attention. At present, the generation, migration, and reaction mechanism

of photo generated electron hole pairs in photocatalytic processes have been preliminarily

explored. In the future, we will further explore the micro mechanisms of catalytic reactions and

gain a deeper understanding of intermediate species and reaction pathways in the development

of efficient catalysts and catalytic processes. And optimize the structure and electronic

properties of photoelectrode materials to improve the separation and transmission efficiency of

photogenerated carriers.
