N掺杂和光化学合成CoSex助催化剂改性石墨相氮化碳以提高其光催化产氢性能
Modification of Graphite Carbon Nitride by Nitrogen-Doping and in situ Loading CoSex as Co-Catalyst by Light-Assisted Synthesis for Enhanced Photocatalytic Hydrogen Production
摘要
Abstract
Developing an efficient photocatalyst for hydrogen production is crucial for the conversion of solar energy to hydrogen.An efficient photocatalytic hydrogen evolution material was prepared by altering the graphite carbon nitride(CN)through nitrogen-doping and employing CoSex as a co-catalyst through a photochemical synthesis route.The optimal photocatalytic performance of the material is 285 times higher than that of CN.Photoelectrochemical experiments demonstrate that nitrogen-doping and introducing CoSex can effectively promote the separation of photogenerated charge carriers,thus increasing the hydrogen evolution activity of CN.This work may provide new perspectives for the preparation of novel photocatalysts by photochemical deposition methods.关键词
