摘    要:It is a challenge to develop single polymer-based photocatalyst for overall water splitting without adding sacrificial agents due to the insufficient driving force for charge separation and the lack of active sites of organic polymer.Metal oxyhyroxides are widely acted as co-catalyst for photoelectrocatalysis oxygen evolution reaction.Here,we firstly report the peryleno1,12-bcd]thiophene sulfone-based linear co-polymer PS-5 for photocatalytic overall water splitting by photo-depositing simple and low-cost cocatalyst FeOOH under the visible-light illumination.The density functional theory(DFT)calculations and experimental results indicated clearly that the oxygen vacancies-richβ-FeOOH can effectively promote the separation of photo-generated excitons and provide active sites for photocatalytic oxygen evolution reaction.As a result,the average H2and O2production rates of optimized PS-5/β-FeOOH-0.2M reach at~170 and~76.6μmol h-1g-1,respectively,with a stoichiometric ratio at about 2:1.This work provides a simple and low-cost method for the preparation of overall water splitting system based on polymer photocatalyst.
