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, CH 2 (OH) 2 is the most efficient sacrificial agent in a nontrivial mechanism in acidic media. Our work aims to deepen understanding of the reaction mechanism and guidelines for selecting the best sacrificial agent. More information can be found in the Full Paper by R. Bar‐Ziv, T. Zidki, et al. (DOI: 10.1002/chem.202103040).
