Preparations And Electrochemical Properties Of Co@Nc Nanocomposites Based On Zif-67, Xiao-Li Tan, Deng-Hong He, Xing-Wang Zhang

Journal of Electrochemistry

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) …
