Abstract

Development of an efficient and inexpensive water oxidation electrocatalyst using the earth-abundant elements is still far to go. Herein, a novel strategy has been demonstrated for developing the OER electrocatalyst by doping Co(II) in to a three-dimensional Cd-based MOF that contains a naked pyridine moieties in the form of uncoordinated ligand. Electrochemically active CoCd-MOF was resulted through the doping of Co(II) into the inactive Cd-MOF. CoCd-MOF exhibited very high catalytic activity in water oxidation reaction. An overpotential of 353 mV is required to produce an anodic current density of 1 mA/cm² under alkaline conditions. Further, the CoCd-MOF exhibits remarkable recyclability over 1000 cycles.
