开发一种高效的产氢光催化剂对于将太阳能转化为氢能至关重要。该研究将氮掺杂石墨相氮化碳(CN)与光化学合成得到的助催化剂CoSeA相结合,通过原位合成制备了一种高效的光催化产氢材料。该材料的最佳光催化性能较CN提高285倍。光电化学试验表明,氮掺杂和引入CoSex可以有效促进光生电荷载流子的分离,从而提高CN的产氢活性。该工作为利用光化学沉积方法制备新型光催化剂提供了新的视角。
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
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.
