Nickel‐borate nanosheets array on titanium mesh (Ni−Bi NA/TM) was derived from NiSe 2 nanosheets array on titanium mesh (NiSe 2 NA/TM) by electrochemical transformation. As a three‐dimensional electrode, Ni−Bi NA/TM exhibited high catalytic activity toward the oxygen evolution reaction and required a low overpotential of 430 mV at 10 mA cm −2 in 0.1 m potassium borate (pH 9.2), with outstanding long‐term stability and high turnover frequency.
