A mononuclear ruthenium complex [Ru(tpy)(bpg)H2O]2+ bearing a bipyridine glycoluril ligand (bpg) = 4b,5,7,7a-tetrahydro-4b,7a-nepiminomethan-oimino-6H-imidazo[4,5-f][1,10]phenanthroline-6,13-dione acts as a robust water oxidation catalyst (WOC) at pH = 1 using Ce(iv) as a sacrificial oxidant.

Photocatalytic proton reduction and water oxidation have been studied in a tris(2,2’-bipyridyl)ruthenium complex-catalyst system. Pyrochlore-type oxides have been used as proton reduction catalysts with a sacrificial electron donor (Na2EDTA) at pH 7 and as water oxidation catalysts with a sacrificial electron acceptor (K2S2O8) at pH 3. Rate constants for the proton reduction were estimated on the basis of photochemical processes. Yb2Ru2O7-δ was found to be the most active catalyst for proton reduction and water oxidation catalyst in this system.
