光电催化（PEC）技术涉及对TiO2薄膜电极施加电偏压，由于其高降解效率，已被广泛应用于难降解有机污染物的降解。本文回顾了使用 TiO2 膜电极 PEC 降解难降解有机污染物的最新进展。研究了各种TiO2薄膜电极的制备和应用，以及影响PEC活性的参数，如晶体结构、薄膜厚度和基底材料、施加的电偏压、溶液pH值和电导率。讨论了通过在TiO2薄膜电极上掺杂金属和非金属离子来提高PEC活性。 PEC 降解有机污染物的机制和动力学也得到了强调。
Photoelectrocatalytic (PEC) technology involved applying an electrical bias to a TiO2film electrode, has been widely applied to the degradation of refractory organic pollutants, owing to its high degradation efficiency. This paper reviews recent developments in the PEC degradation of recalcitrant organic contaminants using a TiO2film electrode. The preparation and application of various TiO2film electrodes have been investigated, as well as the parameters that influence PEC activity such as the crystal structure, the film thickness and substrate material, the applied electrical bias, the solution pH and conductivity. The improvement of PEC activity by doping the TiO2film electrode with metal and non-metal ions has been discussed. The mechanism and kinetics for the PEC degradation of organic pollutants have also been highlighted.
