Biomass‐Derived Hetero Atom‐Doped Porous Carbon for Enhanced CO ₂ Adsorption

ABSTRACT The emission of carbon dioxide (CO 2 ) and its impact on global warming have shown exponential growth in recent decades. Hence, the mitigation of CO 2 emissions is indeed important. Among the developed protocols, the selective and effective capture of CO 2 using porous materials is foremost. Though the porous materials demonstrated excellent CO 2 capture activity, the synthesis of those porous materials using chemical precursors limits their applicability. As a consequence, serious attention has been given to the synthesis of porous materials using biomass. Several biomass components have been reported to synthesize heteroatom‐doped porous carbon (PC) materials, which proved to be an excellent adsorbent for CO 2 capture and conversion to utilitarian products. This review will focus on the different synthetic techniques reported for the synthesis of PC using biological materials. Here, we elucidate the synthesis of the heteroatom (N, S, P, O, B)‐doped porous carbon materials. Furthermore, CO 2 capture has been discussed concerning the influence of pore size and heteroatoms. Lastly, the conversion of CO 2 to utility products has been covered. We foresee that the information gathered regarding the synthesis of PC using biomass and its conversion to utility products will provide a strong platform to researchers and learners.
