Preparation of Activated Carbon Derived from Tobacco and its Electrochemical Properties

Tobacco was carbonized two steps in KOH as an activator to produce high-performance carbon materials for supercapacitors. To make bio-carbon, tobacco was pre-carbonized at 400 degrees C to build a preliminary carbon skeleton, then activated with KOH and carbonized at 800 degrees C for 1 hour. SEM, XPS, Raman, and BET were used to check the physicochemical properties of the tobacoo porous carbon materials. In contrast, GCD, CV, and EIS were used to determine electrochemical properties. PC3's outstanding electrochemicalperformance is due to its vast surface area (1728.5 m(2)/g), shortening ion diffusion routes and allowing for rapid electron migration. The tobacoo porous carbon PC3's specific capacitance is 324F/g. Thus, tobacco can be used as a material for supercapacitors and electrodes.
