The increasing concentration of carbon dioxide (CO₂) in the atmosphere due to human activities is a major contributor to global climate change. As a result, effective carbon sequestration strategies are crucial for mitigating the impacts of climate change. Among various techniques, adsorption has emerged as a promising method for CO₂ capture and sequestration. This review provides a comprehensive overview of adsorption-based technologies for carbon sequestration, focusing on the materials used, adsorption mechanisms, and key parameters influencing performance. Adsorbents such as activated carbon, metal-organic frameworks (MOFs), zeolites, and biochar are examined for their efficiency, capacity, and regeneration capabilities. Additionally, the environmental and economic aspects of these materials are discussed in the context of their practical application. The review highlights the advantages and challenges associated with adsorption processes, offering insights into potential advancements and future directions for improving the efficiency of carbon sequestration.
