金属/磷酸银复合光催化剂的研究进展

磷酸银被发现是一种具有极高活性的可见光催化剂而受到密切关注。但单独的磷酸银半导体具有稳定性差等缺点,限制了其进一步应用。梳理发现构建金属/磷酸银复合光催化剂可以实现磷酸银光生载流子的有效分离,同时还可发挥纳米金属粒子的等离子体共振效应,从而提高复合光催化剂的催化活性和稳定性,此外还可借助其他助剂构建三元复合金属/磷酸银光催化剂。本综述对磷酸银光催化剂的改性研究具有指导意义。

Research Progress of Metal/Silver Phosphate Composite Photocatalyst

Silver phosphate (Ag3PO4) is found to be a highly efficient photocatalyst and receives great attention. However, single silver phosphate semiconductor has a poor stability, which limits its further application. It's found that preparing metal/silver phosphate composite photocatalyst can achieve effective separation of carriers of silver phosphate, and can also utilize the surface plasmon resonance effect of metal nanoparticles, which can improve the activity and stability of silver orthophosphate. Furthermore, using other auxiliary can also build the ternary metal/silver orthophosphate composite photocatalyst. In this paper, modification researches of silver orthophosphate photocatalyst were discussed.
