摘要：

Lignocellulosic biomass such as plants and agricultural waste are ideal to tackle the current energy crisis and energy-related environmental issues.Carbon-rich lignin is abundant in lignocellulosic biomass,whose high-value transformation and utilization has been the most urgent problem to be solved.Herein,we propose a method for the preparation of porous carbon from lignin employing an H3PO4-assisted hydrothermal method.We characterize the as-prepared lignin-derived porous carbon and investigate its potential for energy storage.After assisted hydrothermal treatment followed by carbonization at 800℃,the lignin-derived porous carbon displays a high specific capacitance(223.6 F·g-1 at 0.1 A·g-1) and excellent cycling ability with good capacitance retention.In this present study,the resultant lignin-derived porous carbon was used as the electrode of a supercapacitor,illustrating yet another potential high-value use for lignin,namely as a candidate for the sustainable fabrication of main supercapacitor components.
