| 中文摘要: |
| 工业发展与人类活动导致大气中CO2浓度逐年升高, 引发一系列生态环境问题. 将CO2光催化转化为高附加值化学物质不仅有利于缓解环境压力,也可以带来额外经济价值. 然而, 由于多电子利用效率低和C―C偶联动力学缓慢, 光还原CO2制多碳产品面临产率低和选择性差等挑战. 光催化剂活性位点调控能够有效解决上述问题. 我们综述了近几年用于光还原CO2催化剂表面活性位点设计的研究进展, 主要包括缺陷位点、 金属位点以及掺杂位点等, 从活性位点的角度为光还原CO2催化剂设计提供新视角, 并对开发高效光催化剂具有启发意义. |
| 英文摘要: |
| Industrial development and human activities have led to an increase in CO2 concentration in the atmosphere every year, causing a series of ecological and environmental problems. The photocatalytic conversion of CO2 into high value-added chemical substances not only helps to relieve environmental pressure, but also brings additional economic value. However, due to the low multi-electron utilization efficiency and slow C―C coupling kinetics, the photoreduction of CO2 to polycarbon products faces challenges such as low yields and poor selectivity. Photocatalyst active site modulation can effectively solve these problems. This review summarizes the recent research progress on the design of active sites on the surface of photoreduced CO2 catalysts, mainly including defective sites, metal sites and doping sites, to provide a new perspective on the design of photoreduced CO2 catalysts from the perspective of active sites and to inspire the development of efficient photocatalysts. |
