英文摘要	The development of an efficient catalyst for electrolytic water oxidation under neutral or near-neutral environment remains a great challenge. In this communication, we developed a high-performance cobalt-borate nanowire array on a Ti mesh (Co-Bi NA/Ti) from a CoSe2 nanowire array via rapid topotactic conversion. As a three-dimensional water oxidation electrode, such Co-Bi NA/Ti, demands only 420 mV to drive a geometrical catalytic current density of 10 mA cm(-2). It exhibits superior activity when compared to most of the reported non-precious metal catalysts working under benign conditions. In addition, Co-Bi NA/Ti also displays good stability and high turnover frequency (0.59 s(-1) at an overpotential of 600 mV) in 0.1 M potassium borate (pH: 9.2). This novel research finding has paved a new path for developing highly active oxygen evolution reaction electrocatalysts in near-neutral media.
