ABSTRACT
This study has outlined and described the synthesis of different carbon nanomaterials by submerged liquid plasma (SLP) processes for energy applications such as Li-type batteries, capacitors, solar cells, and hydrogen production. The nanocarbon synthesized by the SLP process has been identified as a clean and sustainable technology. SLP has emerged as a simple, low–capital cost, high-yield, and environmental-friendly approach for the synthesis of different forms of nanocarbon. The production of nanostructured carbon materials by the SLP process from organic or aqueous solvents is a fascinating subject in material science today. However, the generation of plasma in an aqueous or organic solvent is not well understood due to the fast-moving electrons, positive ions, excited atoms or molecules, radicals, ultraviolet (UV) light, and the strong electric field in the solutions. In this chapter, the generation of plasma in different aqueous and organic solvents, the reaction mechanisms, the formation of different nanocarbons, and their application in the fields of battery, fuel cell, and capacitor are discussed in detail.
