摘要 以[NH_4]_2MoS_4和CuCl为原料,合成了一系列铜钼基硫氧化物催化剂,并利用X射线衍射(XRD),UV-Vis漫反射光谱、X射线荧光(XRF)等化学物理手段对其进行了表征,制备的催化剂对光表现出较强的吸收特性,同时研究了该系列催化剂在可见光条件下的光催化制氢性能,并考察了反应温度和反应时间对催化剂产氢活性的影响。结果表明,在140℃条件下水热24h合成的催化剂制氢性能最好,平均产氢速率为10.7μmol/h·g。 A series of new cuprous oxythiomolybdate catalysts were prepared by hydrothermal method based on Ammonium Tetrathiomolybdate reacting with cuprous chloride, and were characterized by XRD, UV-Vis spectra and XRF. The cata- lysts exhibit strong absorption in all wave range. These catalysts can produce hydrogen under visible light irradiation in an aqueous Na2S-Na2SO3 media. Meanwhile, the influence of the reaction temperature and time on the activities of the catalysts was investigated. The results indicate that the catalyst activity under hydrothennal condition for about 24 hours at 140℃ is the highest, and the hydrogen production rate is around 10.7μmol/（h· g）.
