Abstract
This study investigates the effect of activation temperature on the surface chemistry of coconut shell-based activated carbon (CSAC), a widely utilized material in environmental and industrial applications such as water and air purification, energy storage, and environmental management. By analyzing various physicochemical properties, including surface area, pore structure, and functional groups, this paper provides insights into how temperature influences the adsorption capacity and overall efficiency of activated carbon. The results show that as the activation temperature increases, the surface area and micropore volume of CSAC increase, while the amount of surface functional groups like oxygenated species decreases. The research underlines the critical role of activation temperature in optimizing the characteristics of CSAC for specific applications and highlights the need for temperature-controlled activation methods in industrial-scale carbon production.
