摘要
采用两步水热法制备了分散性较好的镉锌硫基/氮掺杂氮化碳(Cd_(0.5)Zn_(0.5)S/N-g-C_(3)N_(4))复合催化剂。利用扫描电子显微镜、透射电子显微镜、X射线光电子能谱和X射线衍射仪对所制备的催化剂微观形貌和结构进行表征,并通过瞬态光电流法和气相色谱仪对其产氢性能进行分析。结果表明,Cd_(0.5)Zn_(0.5)S/N-g-C_(3)N_(4)复合催化剂具有较好的催化性能,产氢速率为20.431μmol/h,Cd_(0.5)Zn_(0.5)S/N-g-C_(3)N_(4)复合光催化剂有较高的氧化还原电势和电荷载体的快速迁移能力。
Cadmium-zinc-sulfur-based/nitrogen-doped carbon nitride(Cd_(0.5)Zn_(0.5)S/N-g-C_(3)N_(4))composite catalyst with a good dispersity is prepared by means of two-step hydrothermal method.The micro morphology and structure of the prepared catalyst are characterized by scanning electron microscope,transmission electron microscope,X-ray photoelectron spectroscopy and X-ray diffraction.Its hydrogen production performance is evaluated by transient photocurrent method and gas chromatograph.The results indicate that Cd_(0.5)Zn_(0.5)S/N-g-C_(3)N_(4) composite catalyst has better catalytic performance,with a hydrogen production rate of 20.431μmol·h^(-1).Cd_(0.5)Zn_(0.5)S/N-g-C_(3)N_(4) composite photocatalyst has high redox potential and rapid charge carrier migration ability.
