| 摘 要： | 采用一步煅烧法使类石墨烯碳氮化合物(g-C_3N_4)和磷化镍(Ni_2P)复合并对其光催化产氢性能进行研究.利用X射线粉末衍射、透射电镜、X射线光电子能谱、紫外可见光谱对该复合催化剂的组成、形貌等进行了表征.研究了不同含量的Ni_2P以及不同牺牲剂对g-C_3N_4/Ni_2P光催化性能的影响.与单独的g-C_3N_4相比,该复合催化剂的光催化产氢速率提高了13倍,可以达到165μmol g~(-1)·h~(-1).利用光电化学和光致发光光谱等技术对该复合光催化剂的光催化产氢机理进行研究,结果表明Ni_2P在高效分离光生载流子方面起了关键作用,并且g-C_3N_4和Ni_2P的复合产生了协同效应加速了电子-空穴对的分离,提高了光催化产氢性能.
