摘要：
Taking the Cu-based photocathode for electrocatalytic reduction of CO2 as the research object．First，the basic principles of photocatalysis，electrocatalysis，and photoelectrocatalysis were analyzed，and the main advantages of the photoelectrocatalytic system were summarized． Second，strategies to enhance the performance of Cu-based photocathodes were analyzed in terms of improving light absorption，inhibiting photocorrosion，promoting carrier separation，and optimizing interfacial reactions． By adjusting the morphology of the catalyst，loading light-absorbing semiconductors and doping elements，the light-absorbing ability could be improved． The photocorrosion can be effectively inhibited by wrapping a protective film on the surface． The carrier separation rate and transport efficiency could be effectively improved by surface hole engineering or the introduction of graphene/ reduced graphene oxide，metal organic framework，carbon nanotubes and other materials． The interfacial reactions could be optimized by increasing active sites，introducing LSPR，and improving CO2 adsorption performance． Then，the latest research progress in continuous flow reactor design was analyzed． Finally，the technical problems to be solved in the development of Cu-based photocathode were prospected. © 2023 Huazhong University of Science and Technology.
