| 摘 要： | 以连续流动进Ｈ２Ｓ气体系统，在室温条件下研究了用Ｘｅ灯照射含有催化剂的ＮａＯＨ水溶液时，Ｈ２Ｓ光催化分解为Ｈ２气和元素Ｓ的反应。分别采用ＣｄＳ、Ｖ２Ｏ５／ＴｉＯ２和Ｖ２Ｏ５／Ａｌ２Ｏ３为催化剂，考察了产氢量与介质中ＮａＯＨ含量及照射时间的关系。讨论了光催化分解Ｈ２Ｓ的反应机理。结果表明，连续流动通入Ｈ２Ｓ气体进行光催化分解的方法是可行的，并接近实际可能应用的情况。

| Abstract: | The Photocatalytic cleavage of H_2S into H_2 was studied in a continuous flow systemand alkaline aqueous solution under the illumination of Xe-lamp.CdS,V_2O_5/TiO_2 andV_2O_5/Al_2O_3 were used as catalysts. The hydrogen amount was measured as a functionof the amount of NaOH in the aqueous solution and the irradiation time.The reactionmechanism of the photocatalytic decomposition of hydrogen sulfide was discussed.Theresults show that this continuous flow method is feasible and more near the practicalsituation in decomposition of hydrogen sulfide. |
