The Role of Common Alcoholic Sacrificial Agents in Photocatalysis: Is It Always Trivial?

HER photocatalysis: Choosing the right sacrificial agent! The cover art features the alcoholic hole-scavenger requirements for photocatalytic hydrogen evolution. The desired sacrificial agent forms a relatively strong reducing radical and has an oxidized form that is not a good electron acceptor, which might suppress the HER process. Methanol, fulfilling these requirements, is an excellent choice. Moreover, CH2(OH)2 is the most efficient...
