Growing concerns about greenhouse gas emissions have driven significant efforts toward developing advanced materials for the capture and removal of carbon dioxide (CO₂) from different environments. Among these, biochar-based engineered materials have emerged as promising sorbents for physical adsorption and separation processes, owing to their tunable structure, surface functionality, and potential for scalable production. This review summarizes recent advances in the preparation and application of biochar-based engineered materials for CO₂ capture, highlighting the influence of synthesis methods on their structural properties and adsorption performance. A comparative analysis of different biochar-derived materials is presented, focusing on adsorption capacity, selectivity, and reusability.
