Facile synthesis of biomass-derived porous carbons incorporated with CuO nanoparticles as promising electrode materials for high-performance supercapacitor applications

Supercapacitors with large capacity, good stability and low cost are attractive to the development of energy storage technology. Herein, a new method for preparing biomass-derived carbon materials incorporated with CuO nanoparticles is proposed using cheap peanut shells as the carbon resource and copper acetate as the CuO precursor. The as-prepared CuO-AC sample retains a large BET surface area of 2640.55 m2/g with hierarchical micro-mesoporous...
