摘要：

Green nanotechnology is now emerging to address society's global sustainability issues by recycling numerous industrial and bio-wastes to produce functional carbonaceous nanomaterials like biochar, 2D graphene, graphene oxide, carbon nanotube (CNT), activated carbon (AC), etc. In this study, we have synthesized AC via the hy-drothermal decomposition approach of the walnut shell under high temperature and pressure in a hydrothermal autoclave at temperature ranges from 200 to 250 celcius. The synthesized AC has a high specific surface area of 408.8 m2/g. It has an excellent specific capacitance of 204F/g at 1 A/g of current density with good cyclability up to 10,000 cycles.
