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.

可见光作用下结晶类石墨氮化碳参与的苯甲醇溶液光催化析氢

已经确定，当取代基的给电子能力增加时，苯甲醇及其一些衍生物的水-乙腈溶液在可见光作用下在结晶石墨状氮化碳的参与下析氢的效率增加苯甲醇的对位增加。最高的 H ₂释放速率为 720 μmol·h ^–1 ·g ^–1（在 405 nm 处的量子产率 Φ = 22%）是在 40 °C、0.1 M HCl 存在下的 4-甲氧基苄醇溶液中实现的。
