Abstract

It is necessary to develop an inexpensive catalyst for the replacement of precious metal catalysts (such as RuO2, IrO2). In this article, the metal organic framework ZIF-67 was synthesized by solvothermal method at room temperature, and then the high temperature carbonization was used to prepare the nitrogen-doped carbon-based composite material Co@NC with the Co nanoparticle inside. The effects of the carbonization temperature on surface morphology, chemcial composition and electrocatalytic property were investigated. Most importantly, the Co@NC catalyst with the best morphology and structure was synthesized, and its catalytic activity and stability toward oxygen evolution reaction (OER) were studied under alkaline conditions. Electrochemical test results showed that the Co@NC catalyst prepared at 700 ℃ had higher OER catalytic activity and excellent stability. It only required an overpotential of 266 mV for reaching the current density of 10 mA·cm-2, with good stability over 40 h.
