Abstract
Abstract The synthesis of high-performance porous carbon materials via carbonization of environment-friendly biomass fits perfectly with the concepts of sustainability and green chemistry. Herein, we report lignocellulose-derived porous carbon materials and their high capacitive deionization (CDI) performance, achieving a high salt adsorption capacity of 12.5 mg g−1 and good cycling stability. The preparation of porous carbon materials via direct carbonization of lignocellulose provides a number of advantages, including cost-effectiveness, high production yields, and environment-friendliness, which are ideal for industrial application of CDI. This work not only suggests novel insights to design and prepare high-performance carbon materials but also highlights the significance of green chemistry using nature-provided biomass materials to synthesize porous carbon materials.
