Sulfur-Doped Carbons from Durian Peels, Their Surface Characteristics, and Electrochemical Behaviors.

Durian peels are an agricultural waste in Asian countries, including Thailand, Indonesia, and Malaysia, which can be used as a precursor for the production of activated carbon. The objective of this work is to produce activated carbon from durian peels by chemical activation using sodium sulfite (NaSO) as an activating and sulfur-doping agent. The process parameter investigated in this study was the activation temperature (500-900 °C) at a fixed impregnation ratio (durian to activating agent of 1:1, by weight).
