| 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 H2S into H2 was studied in a continuous flow systemand alkaline aqueous solution under the illumination of Xe-lamp.CdS,V2O5/TiO2 andV2O5/Al2O3 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. |
