Development of a CO<sub>2</sub> adsorbent and CO<sub>2</sub> conversion catalyst using the physicochemical properties of hollow carbon

CO2 capture as well as thermocatalytic and electrocatalytic CO2 conversions provide promising ways for achieving global carbon neutrality, and the development of corresponding advanced adsorbents and catalysts is important but challenging. Hollow-structure carbon materials with striking features, including a unique cavity structure, good permeability, large surface area, good electrical conductivity and an easily readily functionalized surface, are flexible platforms for designing high-performance adsorbents and catalysts. This review describes the author's recent research work ranging from the development of CO2 adsorbents to thermocatalytic and electrocatalytic CO conversion catalysts that take advantage of the interesting physicochemical properties of hollow-structure carbon materials.
