CoPC/g-C3N4 composite catalyst is prepared via a hydrothermal method,and its photocatalytic performance for phenol degradation is studied.The relationship between structure and properties of the catalyst is analyzed by means of FT-IR,SEM,XRD,ICP,XPS and electrochemical testing techniques,and the possible photocatalytic reaction mechanism is proposed.Experimental results show that the photocatalytic degradation performance of CoPC/g-C3N4 increases by 1.7 times than that of single g-C3N4,and the degradation rate of phenol reaches 82％over CoPC/g-C3N4.Characterization results show that the improvement of photocatalytic performance is attributed to the improvement of photo-absorption performance of CoPC/g-C3N4 under CoPC loading.The loading of CoPC can effectively enhance the migration rate of photogenerated carriers,thereby improving the catalyst's performance in photocatalytic degradation of phenol.
