Nickel-borate nanosheets array on titanium mesh (Ni-Bi NA/TM) was derived from NiSe nanosheets array on titanium mesh (NiSe 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 in 0.1 m potassium borate (pH 9.2), with outstanding long-term stability and high turnover frequency.
钛网上的镍硼纳米片阵列（Ni-Bi NA/TM）是通过电化学转化从钛网上的硒化镍纳米片阵列（NiSe NA/TM）衍生而来的。作为一种三维电极，Ni-Bi NA/TM对析氧反应表现出高催化活性，在0.1 m硼酸钾（pH 9.2）中，在10 mA cm时需要430 mV的低过电位，具有出色的长期稳定性和高周转频率。
