Abstract
A nickel-based oxygen evolution catalyst, nickel-bicarbonate (Ni-Ci), was electrochemically deposited for varying intervals on the surface of W-doped BiVO? in a 0.1 M bicarbonate electrolyte at neutral pH conditions. Optimally deposited Ni-Ci successfully catalyzed the photoelectrochemical water oxidation of W-doped BiVO? photoelectrodes under benign pH conditions as evidenced by an enhanced photocurrent during photocurrent-potential characterizations. Efficient charge-transfer at the electrode-electrolyte interface in the presence of the Ni-Ci catalyst improved the kinetics of the W-doped BiVO? photoanodes. The W-doped BiVO? photoanodes integrated with a Ni-Ci oxygen evolution catalyst exhibited a large cathodic shift ([similar]371 mV) in the onset potential for water oxidation and maintained a stable photocurrent.
