摘要: 硫化铜作为一种重要的过渡金属硫化物在催化、纳米开关和储能等领域具有广泛的应用。本文采用简易水热法，以柠檬酸为表面活性剂，硫酸铜和硫脲为原料，反应10 h成功合成CuS纳米粒子。采用XRD、SEM等手段对产物进行了表征分析。以甲基橙为目标污染物，分别在紫外光和可见光照射下考察了CuS纳米粒子的光催化性能。结果表明：柠檬酸浓度会显著影响CuS的尺寸和分散性；CuS纳米粒子同时具有紫外和可见光催化活性。
Abstract: Copper sulfide as an important transition metal sulfide is widely used in catalytic, nanoswitch and energy storage. In this paper, CuS nanoparticles were successfully synthesized by a facile hydro-thermal method, using citric acid as surfactant and copper sulfate and thiourea as raw materials. The as-prepared samples were characterized by XRD and SEM. And the photocatalytic properties of CuS nanoparticles were investigated by using methyl orange as pollutant under ultraviolet and visible light irradiation. The results show that the size and dispersibility of CuS nanoparticles is determined by the citric acid concentration. And the CuS nanoparticles exhibit photocatalytic ac-tivity under both ultraviolet and visible light irradiation.
