摘要
采用水热法制备CoPC/g-C3N4复合催化剂,并研究其光催化降解苯酚的性能。通过FT-IR、SEM、XRD、ICP、XPS以及电化学测试技术分析催化剂结构和性能关系,提出可能的光催化反应机理。结果表明,相比于单一g-C3N4,CoPC的负载使复合催化剂CoPC/g-C3N4的光催化降解性能提升了1.7倍,CoPC/g-C3N4的苯酚降解率达到82%。光催化性能的提升归因于CoPC的负载提升了CoPC/g-C3N4复合催化剂的光吸收性能,CoPC的负载可以有效增强光生载流子迁移速率,从而提升了光催化降解苯酚的性能。
Abstract
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.
