摘　　要：以还原氧化石墨烯(rGO)作为载体,通过简单的两步水热法合成了一种三维组装的Zn_(0.2)Cd_(0.8)S/rGO复合材料,其在可见光下可有效地通过水裂解产生氢气.采用XRD、SEM、TEM、Raman和紫外可见漫反射等手段,分析研究了ZCS-G(x)复合材料的物相组成和显微结构,并对其进行了光催化产氢性能测试.研究结果表明,样品ZCS-G(1.5)的产氢率是在相同反应条件下所生成Zn_(0.2)Cd_(0.8)S固溶体材料(ZCS-G(0))的2.64倍;在对其进行循环产氢测试时,发现在相同的反应条件下循环测试3圈后(12 h)性能几乎没有下降,说明样品ZCS-G(1.5)具备优异的稳定性.因此,ZCS-G(1.5)材料在可见光照射下可以用作一种具有应用前景的水裂解产氢光催化剂.In this study,the three-dimensional self-assembled Zn0.2Cd0.8S/rGO material synthesized by a simple two-step hydrothermal method using rGO as the carrier,which can generate hydrogen by water splitting under visible light.The phase composition and microstructure of ZCS-G(x)composites were analyzed by XRD,SEM,TEM and Raman,and their photocatalytic H 2-production properties were tested.The hydrogen production rate of the sample ZCS-G(1.5)is 2.64 times of the sample(ZCS-G(0)),a solid solution material Zn0.2Cd0.8S that prepared at the same reaction conditions.Further,we conducted a cyclic test and found that it still have excellent stability after 3 cycles(12 h)of cyclic test under the same reaction condition,it indicates ZCS-G(1.5)sample has excellent stability.The above results show that ZCS-G(1.5)material can be served as a photocatalyst with a promising application prospect for splitting of water under visible light.
