The narrow band-gap and long life-time of photo-generated charges endow CdS with much higher photocatalytic hydrogen evolution (PHE) activity over other photocatalysts. Thus, CdS based materials are considered to be most promising photocatalysts for PHE activity and stability. In this work, graphitic carbon nitride (GCN) is used as sacrifice agent to synthesize is nitrogen and carbon co-doped CdS nanoparticles with of uniform small size and higher specific surface area via hydrothermal reaction. Besides, co-doping of nitrogen and especially carbon leads to electron penetration to CdS results in tuned band structure of doped CdS with down-shifted conducting band and valance band positions. Moreover, the doped heteroatoms act as charge trapping centers that enhance charge separation within CdS particles endowing their photo-generated charges with longer life-time in compared with that of bare CdS. Benefited from non-metallic heteroatoms doping, obviously increased PHE activity and stability of CdS under visible light irradiation are achieved.

光生电荷的窄带隙和长寿命使 CdS 具有比其他光催化剂高得多的光催化析氢 (PHE) 活性。因此，CdS 基材料被认为是最有前途的 PHE 活性和稳定性的光催化剂。在这项工作中，使用石墨氮化碳（GCN）作为牺牲剂，通过水热反应合成了具有均匀小尺寸和更高比表面积的氮和碳共掺杂的 CdS 纳米粒子。此外，氮特别是碳的共掺杂导致电子渗透到 CdS 导致掺杂 CdS 的带结构调整，具有向下移动的导带和价带位置。而且，掺杂的杂原子充当电荷俘获中心，增强了 CdS 粒子内的电荷分离，与裸 CdS 相比，它们的光生电荷具有更长的寿命。得益于非金属杂原子的掺杂，可见光照射下CdS的PHE活性和稳定性明显提高。
