The rising concentration of carbon dioxide (CO₂) in the atmosphere underscores the critical need to develop efficient, scalable, and sustainable carbon capture technologies. Activated carbon (AC) is one of the materials currently being widely developed for carbon capture. The effectiveness of AC for carbon capture depends on its characteristics, such as surface area and functional group content, which vary with the synthesis process. This comprehensive review presents an in-depth evaluation of the synthesis pathways for AC derived from agricultural waste, with particular attention to activation and modification techniques to enhance CO₂ adsorption. It also further examines key parameters influencing the physicochemical properties of these materials, including pore structure, surface area, and surface chemistry. The review process follows the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines to ensure transparency and reproducibility. Inclusion and exclusion criteria were defined to identify the most relevant studies and to systematically collect and synthesize pertinent data. The review identified that chemical activation, particularly with KOH, H₃PO₄, and ZnCl₂, substantially enhances the surface area, pore development, and surface functionality of AC, thereby improving CO₂ adsorption capacity. Among various activation techniques, KOH activation consistently yields the highest specific surface areas and well-developed microporous structur...
