Research Progress of Hydrothermal/Pyrolytic Conversion of Lignocellulose into Porous Carbon Electrode Materials for Supercapacitors
Recently,the high-value conversion and utilization of lignocellulose have attracted wide attention.Converting it into porous car-bon for supercapacitor through hydrothermal and pyrolysis processes is an important pathway for the high-value utilization of lignocellulose.The research progress on the preparation,formation mechanisms,physicochemical properties,etc.,of hydrochar and biochar was highlight-ed.The focus was on the influence of operating parameters on the physicochemical properties of hydrochar and biochar.The emphasis was on exploring the methods of functionalized preparation of porous carbon from hydrochar and biochar,including optimization methods of pore structure and surface characteristics.
