Abstract

Compared to earlier single site catalysts, greatly enhanced rates of electrocatalytic water oxidation by the Ru carbene catalyst [Ru(tpy)(Mebim-py)(OH2)]2+ (tpy = 2,2′:6′,2′′-terpyridine; Mebim-py = 3-methyl-1-pyridylbenzimidazol-2-ylidene) have been observed. The mechanism appears to be the same with proton coupled electron transfer (PCET) activation to RuV[double bond, length as m-dash]O3+ followed by O–O coupling and further oxidation. An important factor in the enhanced reactivity of the carbene complex may come from increased driving force for the O–O bond forming step.
