Electrocatalytic water oxidation is a rate-determining step in the water splitting reaction. Here, we report one single atom W 6+ doped Ni(OH) 2 nanosheet sample (w-Ni(OH) 2 ) with an outstanding oxygen evolution reaction (OER) performance that is, in a 1 M KOH medium, an overpotential of 237 mV is...
