摘要/Abstract

摘要： 以联吡啶钌络合物Ru(bipy)₃²⁺为光敏剂,甲基紫精MV²⁺为电子交换的中继物,EDTA为电子给体,氯铂酸钾为催化剂,探讨了该体系在可见光照射下,光还原水产氢的结果。提出了用明胶作为铂催化剂的稳定剂,可以提高放氢的速度和保护催化剂不受破坏。讨论了该体系光助催化分解水产氢的可能的机理。

Abstract: A photochemical system is described for the evolution of hydrogen by water decomposition upon xenon lamp irradiation of aqueous solution of following composition: a photosensitizer, Ru (bipy)₃²⁺; a mediator, methylviologen hydrate (MV²⁺); an electron donor, EDTA; and a colloidal platinum catalyst, K₂PtCl₆-gelatin. Both the rate of hydrogen evolution and the stability of colloidal platinum catalyst increase when gelatin is applied. The effect of each component and its concentration on hydrogen evolution is reported. The functions of MV²⁺ in the photochemical system and two possible photoca-talytic mechanisms are discussed.
