Here, Dolui et al. incorporate an enzyme-inspired synthetic outer coordination sphere around a molecular cobalt complex and demonstrate it to be capable of producing H<inf>2</inf> from neutral, aerobic aqueous solution under natural solar irradiation—one of the first examples of homogeneous molecular electrocatalysts that can effectively store solar energy in the H-H bond under benchtop conditions.truecobalt catalyst | electrocatalytic H2 production | natural-sunlight-driven H2 production | outer coordination sphere | oxygen tolerant | photocatalytic H2 productionArticlehttps://doi.org/10.1016/j.xcrp.2019.1000072666386422 January 202031100007arJournal26
