Cu(ii) coordination polymers with nitrogen catenation ligands for efficient photocatalytic water oxidation†
Abstract
A Cu(II) coordination polymer, [Cu(tza)2]n (Htza, tetrazole-1-acetic acid), was investigated as an efficient water oxidation catalyst in the well-established Ru(bpy)32+/S2O82− (bpy = 2,2′-bipyridine) photocatalytic system. The turnover frequency (TOF) was measured to be 1.68 s−1, which is the highest among all reported copper-based photocatalytic water oxidation systems.
