摘要

研究发现,在可见光的作用下,当苯甲醇对位取代基的给电子能力增强时,苯甲醇及其衍生物的水-乙腈溶液在晶体类石墨氮化碳的参与下析氢效率提高。以4-甲氧基苄基醇为溶剂,在0.1 M HCl存在下,温度为40℃,H2的析出率最高,为720 μmol·h-1·g-1(量子产率Φ = 22%,波长为405 nm)。

Photocatalytic Hydrogen Evolution from Solutions of Benzyl Alcohols Under the Action of Visible Light with the Participation of Crystalline Graphite-Like Carbon Nitride

It is established that the effeciency of the hydrogen evolution from water–acetonitrile solutions of benzyl alcohol and a number of its derivatives under the action of visible light with the participation of crystalline graphite-like carbon nitride increases when electron-donating ability of the substituent in the para position of benzyl alcohol increases. The highest H2 evolution rate, 720 μmol·h–1·g–1 (quantum yield Φ = 22% at 405 nm), is achieved in solutions of 4-methoxybenzyl alcohol in the presence of 0.1 M HCl at 40 °C.
