This book systematically introduces the fundamentals, preparation technology, state-of-the-art applications, and future development of biomass-derived porous carbon materials. The authors provide a theoretical foundation that demonstrates the microstructure and physicochemical properties of carbon materials. The fabrication methods, including physical activation methods, chemical activation methods, and advances in other new fabrication methods are explicitly described. The book also identifies many potential applications of biomass (especially biomass-derived porous carbon materials), such as supercapacitors, removal of organic pollutants from water, CO2 capture, photocatalytic application, and farmland restoration. The book will be a valuable resource for researchers, scientists, and engineers working in the field of biomass-derived porous carbon materials, carbon resource development, and environmental protection.
