苯酚是一种重要的有机化工基础原料，应用广泛。近年来，随着苯酚需求量的增加和生产苯酚的主流工艺———异丙苯法与可持续发展的理念冲突，越来越多的研究者将目光投向苯直接羟基化制苯酚。主要从吸收波长范围在紫外光区和可见光区催化剂的角度介绍光催化苯直接羟基化氧化制苯酚的研究进展，当前光催化苯制苯酚研究中，钒氧化物催化剂和贵金属催化剂活性组分易流失，钒氧化物催化剂寿命短，纳米金催化剂活性衰减快，铁系物催化剂和氧化钛催化体系选择性偏低，这也是今后需要解决的重点。%Phenol is an important basic organic raw chemical materials and has a wide range of applica-tion. In recent years,the demand for phenol has been increasing and current main producing process of phenol———cumene process is at variance with sustainable development. Therefore,direct hydroxylation of benzene to phenol has been paid much attention to. In this paper,the research progress in photocatalytic hydroxylation of benzene to phenol from the perspective of the absorption wavelength range of the catalysts in the ultraviolet and visible are mainly described. There are some problems needed to be solved in the study of photocatalytic oxidation of benzene to phenol in the future ,such as the leaching of active compo-nent of vanadium oxide catalyst and noble metal catalyst,short life of vanadium oxide catalyst,decline of nano gold catalyst’s activity and low selectivity of iron oxide catalytic systems.
