摘要： 在太阳能分解水制氢研究中存在的一个问题,是产氢要消耗化学试剂(电子给体),以人们研究得很多的Ru(bpy)32+-MV2+-EDTA-铂催化剂体系为例[1].
关键词: 光敏剂, 电子给体, 光生电势, 光照产氢
Abstract: Phototentials (EL) of proflavin-EDTA,acridine yellow- EDTA,and erythrosin-TEOA aqueous solutions were measured by using SnO2 as working electrode and SCE as reference electrode.EL was compared with the potential of H2 electrode (EH+/H2) at the pH of the photosensitizer-electron donor aqueous solution.It was found that EL>EH+/H2 was the crucial condition for a photosensitizer-donor solution to make H2 photoproduction in the presence of K2PtCl6 For the same Ru(bpy)32+-MV2+-EDTA aqueous solution,it has also been found that the higher its photopotential at different pH of the solution or different concentrations of a component in the solution,the higher its rate of H2 photoproduction in the presence of Pt catalyst.
Key words: photosensitizer, electron donor, photopotential, hydrogen photoproduction
