Construction of high-efficiency CoS@Nb2O5 heterojunctions accelerating charge transfer for boosting photocatalytic hydrogen evolution
文献摘要：
The random movement and easy recombination of photoinduced charges lead to a low conversion effi-ciency for photocatalytic hydrogen evolution.The cocatalyst design is a promising route to address such problem through introducing an appropriate cocatalyst on the semiconductor photocatalysts to construct the high-efficiency heterojunctions.Herein,novel CoS/Nb2O5 heterojunctions were constructed via in-situ loading CoS cocatalyst on the surface of Nb2O5 nanosheets.Through the femtosecond-resolved transient absorption spectroscopy,the average lifetime of charge carriers for 10 wt％CoS/Nb2O5(159.6 ps)is dras-tically shortened by contrast with that of Nb2O5(5531.9 ps),strongly suggesting the rapid charge transfer from Nb2O5 to CoS.The significantly improved charge-transfer capacity contributes to a high photocat-alytic hydrogen evolution rate of 355 pmol/h,up to 17.5 times compared with pristine Nb2O5.This work would provide a new design platform in the construction of photocatalytic heterojunctions with high charge-transfer efficiency.
