Xiong, Xiaoli You, Chao Liu, Zhiang Asiri, Abdullah M. Sun, Xuping Co-Doped CuO Nanoarray: An Efficient Oxygen Evolution Reaction Electrocatalyst with Enhanced Activity It is highly desired to enhance the catalytic activity of oxygen evolution reaction (OER) electrocatalysts made of earth-abundant elements. In this Letter, we report that the OER activity of a CuO nanoarray can be largely enhanced by Co doping. In 1.0 M KOH, the Co-CuO nanoarray on copper foam requires a current densities of 50 and 100 mA cm<sup>–2</sup> at overpotentials of only 299 and 330 mV, respectively. It also shows superior long-term durability over 15 h with a turnover frequency of 0.056 mol O<sub>2</sub> s<sup>–1</sup> at an overpotential of 300 mV. cm;OER activity;oxygen evolution reaction;turnover frequency;CuO nanoarray;15 h;0.056 mol O 2;Enhanced Activity;copper foam;300 mV;density;durability;Co-Doped CuO Nanoarray;Co-CuO nanoarray;overpotential;1.0 M KOH;earth-abundant elements;mA;Co doping;330 mV;Efficient Oxygen Evolution Reaction Electrocatalyst;electrocatalyst 2018-01-29
