Harnessing nature for next-generation CO2 removal
摘要
Achieving carbon neutrality necessitates a variety of strategies, including the adoption of renewable energy with zero carbon emissions, utilization of low-carbon fuels, and significant reduction in anthropogenic emissions, with a strong emphasis on carbon dioxide (CO2) capture technologies. These technologies are essential for significantly lowering atmospheric CO2 levels. Current methods of carbon capture, such as the use of metal-organic frameworks, amine solvents, and ionic liquids, excel in high surface areas, porosity, and reactive functional groups. However, they involve sophistication and costly production processes. This review proposes a shift toward materials engineered from naturally derived compounds and bioinspired mechanisms, enhancing the accessibility and sustainability of CO2 sorption. This prospective aims to explore and bridge advancements in naturally derived or inspired CO2 capture materials and methods, assessing their physical and chemical structures, sorption mechanisms, and capabilities. This article will compare these nature-inspired materials to contemporary artificial technologies, highlighting their potential for the next generation of adsorbent and absorbent materials, including solid, liquid, and mixed-state, characterized by rapid kinetics, high efficiency, sustainability, and stability in CO2 sorption.
