Preparation of activated carbon from coconut shells using mechanical milling method / Mohamad Azzam Aizat Nazali

This project explores the utilization of coconut shell-activated carbon for the optimization of hydrogen storage. The coconut shells were treated thermally and undergone a mechanical milling process in an effort to produce a material with additional microscopic pores to escalate the surface area. This enables the material to hold hydrogen more efficiently. The study experimented with various temperatures and processes in an effort to determine the optimal way to activate the coconut shells. Experiments showed that hydrogen was stored better in chemically treated coconut shells compared to untreated shells, with a 30% increase in storage capacity. Microscopy imaging confirmed that the material now possessed by very small pores and was hence better at storage hydrogen. The study emphasizes that activated carbon derived from coconut shells can be an improved material for storing hydrogen. It can be suggested that various chemical treatments should be tried and long-term storage behavior needs to be studied.
