近年来,国际上关于 Ru(bipy)_3~(2+)/MV~(2+)/EDTA/Pt水溶液体系光致产氢的研究已有报道。其中Ru(bipy)_3~(2+)为光敏剂,MV~(2+)为电子中继物,EDTA为电子源,胶态铂为催化剂。为了使学生了解当前有关这类化学现象的基本原理、操作、进展及其中的电子传递过程,在教学中开出本实验是受到欢迎的。但是,文献中的这些实验是从研究角度出发的,它们在设备、试剂及用量、催化剂制作、光源等方面都有一定的要求。为了使一些条件比
In recent years, the international research on photoluminescence of Ru (bipy) _3 ~ (2 +) / MV ~ (2 +) / EDTA / Pt aqueous solution has been reported. Among them, Ru (bipy) _3 ~ (2+) is a photosensitizer, MV ~ (2+) is an electron relay, EDTA is an electron source and colloidal platinum is a catalyst. In order to enable students to understand the current basic principles of these chemical phenomena, operation, progress and the electron transfer process which, in the teaching of this experiment is welcome. However, these experiments in the literature are from a research perspective and they have certain requirements in terms of equipment, reagents and dosage, catalyst preparation, light sources and the like. In order to make some conditions ratio
