Non-metallic electronic regulation in CuCo oxy-/thio-spinel as OER electrocatalysts
Researchers successfully prepared oxy-spinel of Cu1-xCo2+xO4 nanaoflakes and thio-spinel of Cu1-xCo2+xS4 nanospheres by a facile hydrothermal method. The resulting Cu1-xCo2+xO4 exhibits higher catalytic performances toward OER in alkaline media than Cu1-xCo2+xS4 for water oxidation. Experimentally and theoretically, the superior OER catalytic activity of Cu1-xCo2+xO4 nanoflakes mainly depends on the strongly-electronegativity of oxygen element in spinel structure, which determines the higher valence state of Co active sites in CuCo oxyspinel.
