Abstract

An exponential increase in the atmospheric temperature, destructive environmental effects, and the unreplenishable nature of energy supplies have sparked universal attention to the need to find alternative energy sources, value-added chemical products, and fuel. Biomass-derived material has emerged as a fantastic alternative in this regard. These biomasses contain carbon as a skeletal backbone, allowing science and technology to function to a higher degree. Numerous naturally abundant environmental and agro-wastes have been researched to manufacture porous carbon for supercapacitor electrodes because of their ready availability, outstanding performance, and easy processing techniques. This chapter discusses various environmental waste-derived carbon nanomaterials and general preparation methods, activation processes, recent advancements, challenges, and future perspectives.
