摘要: 以铜粉和硫粉为原料,在四丙基溴化铵和乙二醇(物质的量比1∶3)组成的低共熔溶剂中,分别于不同温度和不同时间内通过单质反应制备出直径为1~2μm 微米球结构的高纯度CuS,并得出其最优反应条件为25℃、6h。用XRD、SEM 等手段对样品进行了表征,XRD表明样品为纯净的CuS晶体。SEM 表明样品具有由纳米片交错连结而成的微米球结构。UV-Vis分析表明样品在紫外光区和可见光区均有较强吸收,其禁带宽度约为1.59eV。测试了样品的光催化性能并探究了H2O2 在催化过程中的重要作用。在光照60min后,亚甲基蓝(10mg/L)、罗丹明B(10mg/L)和甲基橙(10mg/L)的降解率分别达到94.99%、89.90%和69.42%,表明样品具有优越的光催化活性,并且得出H2O2 的加入能显著提高染料的降解率。

Abstract: An elemental-direct-reaction has been carried out to synthesis CuS with sulfur powder and copper powder. CuS with diameter of 1~2 μm is successfully synthesized in deep eutectic solvent of tetrapropylammonium bromide and ethylene glycol (molar ratio=1∶3). It was found that the optimized reaction condition was 25 ℃ by changing reaction parameters such as temperature and time. XRD analysis showed the product was highly purity. SEM indicated the surface of each CuS spheres were covered with many nanoflakes interconnected with each other. UV-Vis analysis showed that the product had strong absorption in both ultraviolet and visible region, the band gap energy of the product was approximately 1.59 eV. The asprepared CuS was tested by the degradation of methylene blue, Rhodamine B and methyl orange under the irradiation of UV Lamp. The degradation rate were up to 94.99%, 89.90%, 69.42% in 60 min and it showed its excellent photocatalytic activity. Moreover, the test also showed that the addition of H2O2 played an important role in the experiment.
