摘要
Acrifiavine dye, with a long-lived triplet excited state, has a strong sensitizing ability for photodriven water splitting when [Co(III)(dmgH)(2)(py)CI] complex is used as a catalyst and triethanolamine as electron donor. This catalytic system is an example of a noble-metal-free homogeneous system for hydrogen generation from water. Moreover, the mechanistic details of the overall reaction pathway, as well as Acriflavine fading, is presented to offer significant guidance to developing more robust photocatalytic systems.
