Abstract：Photoelectrocatalytic (PEC) technology is a new electrochemical-assisted photocatalytic (PC) technology which inhibits the recombination of photoelectron and photohole by adding anode bias resulting in enhancing photocatalytic efficiency.Recently,PEC technology has attracted wide attention since it shows a great application prospect in water treatment.The mechanisms of PEC technology were sketched,and the developments of visible light-responsive photoanode were summarized.PEC reactors classified as slurry PEC reactors,immobilized PEC reactors and composite PEC reactors were separately introduced,followed by their configurations,mechanisms,and features.Moreover,the applications in water treatment and pollutants PEC conversion were also summarized.The shortcomings of PEC technology in water treatment application were discussed and the outlook of this technology was predicted.
