Abstract
The development of cheap, high activity and stability catalysts for oxygen evolution reaction (OER) is of great significance because of its important role in energy storage technology. Herein, flower-like CoSe2-Co3O4-Ag with enhanced electrochemical performance was synthesized by simple methods. The CoSe2-Co3O4-Ag exhibits lower overpotential and higher current density, with an overpotential of 324 mV at the current density of 10 mA⋅cm[Formula: see text] and a Tafel slope of 65.69 mA⋅dec[Formula: see text]. From the ECSA normalized LSV curves, higher electrocatalytic activity for OER is mainly due to the increase of ESCA and conductivity, minor due to adjusting the electronic configuration. These strategies to improve electrochemical active area and conductivity have valuable reference for designing cheap, high activity and stability catalysts.
