摘　　要：通过加热回流和浸渍法制备具有光催化产氢性能的Ni(Ⅱ)配合物/g-C_3N_4复合材料.使用扫描电子显微镜(TEM)和X射线衍射仪(XRD)对复合材料的晶体结构、微观形貌进行表征,同时使用荧光分光光度计对载流子的分离效果进行验证.实验测试了Ni(Ⅱ)配合物/g-C_3N_4复合材料在模拟太阳光下的光催化制氢性能,并对该催化剂的光催化制氢的可重复利用性进行研究.结果表明:在模拟太阳光照射下,该复合材料催化分解水产生氢气的速率约为84. 22μmol/(g·h),与纯相g-C_3N_4相比,光催化产氢性能提升了5倍,且该复合材料具有优异的可重复利用性.Ni （ Ⅱ ） complex/g-C3N4 composite with photocatalytic hydrogen production performance was prepared by heating reflux and impregnation method. The crystal structure and morphology of the composites were characterized by transmission electron microscopy （TEM） and X-ray diffraction （XRD）. The separation effect of the carriers was verified by fluorescence spectrophotometer. The photocatalytic hydrogen production performance of Ni（Ⅱ ） complex/g-C3N4 composite under simulated sunlight was tested, and the reusability of photocatalyfic hydrogen production of the catalyst was studied. The results show that under the simulated sunlight, the rate of hydrogen production from the catalytic decomposition of water is about 84.22 μmol/（ g. h）. Compared with the pure phase g-C3 N4, the photocatalytic hydrogen production performance is increased by 5 times. And the composite material has excellent recyclability.
