以四硫钼酸铵与氯化亚铜在氨水中反应为原料，采用水热法制备了一种新型可见光驱动cu2mos4光催化剂。采用XRD、UV-vis、XRF、SEM等技术对合成的催化剂进行了表征。考察了反应温度和反应时间对催化剂活性和颗粒形貌的影响。结果表明，催化剂在可见光区有较强的吸收。结果表明，在140℃水热条件下制备的光催化剂结晶度好，形状规则，在na2s - na2so3水溶液中可见光照射下产氢活性最高。详细讨论了其性能较好的原因。
A novel visible-light-driven Cu2MoS4photocatalyst was prepared by a facile hydrothermal method using Ammonium Tetrathiomolybdate reacting with cuprous chloride in aqua ammonia. The synthetic catalysts were characterized by XRD, UV–vis spectra, XRF and SEM techniques. The influence of the reaction temperature and time on the activities of the catalysts and the morphology of particles was investigated. The results showed that the catalysts exhibited strong absorption in visible light region. It was found that the photocatalyst prepared under hydrothermal condition at 140°C for about 24h showed good crystallinity with regular shape, and the highest activity for hydrogen production under visible light irradiation in an aqueous Na2S–Na2SO3solution. The reason for its better performance has been discussed in detail.
