Application of Single-atom Catalysts in Photocatalysis for Energy and Environmental Fields
Artificial photocatalytic energy conversion is an attractive strategy for solving energy crisis and environmental problems through a direct solar energy harvesting.Among them,the development of novel photocatalysts with high efficiency and low cost is a central task to promote the application of photocatalytic reactions in the energy and environmental fields.Single-atom catalysts(SACs)have become one of the promising candidates for a wide range of applications in photocatalysts and have attracted much attention in the field of catalysis in recent years due to their unique advantages of maximum atom utilization and excellent catalytic activity.The study briefly introduces the characteristics of SACs and their preparation methods,and focus on summarizing the applications of SACs in photocatalysis,including four applications of photocatalytic hydrogen production,photocatalytic carbon dioxide reduction,photocatalytic nitrogen reduction,and photocatalytic degradation of pollutants,and at the same time,we put forward some future challenges and perspectives in the field of photocatalysis.
