Introducing mesoporous silica-protected calcination for improving the electrochemical performance of Cu@Fe–N–C composites in oxygen reduction reactions and supercapacitor applications

Abstract

The application of zeolite imidazolate framework (ZIF)-based nanomaterials for oxygen reduction reaction (ORR) and supercapacitor (SC) is drastically confined by their quick aggregation and irreversible fusion of metal nanoparticles. Herein,...
