Abstract: The surface microstructure can be influenced by surface environment, weak adsorption, and bonding interactions, leading to the changes of surface electronic states and the configuration of active sites, which affects the mass-energy transfer pathway. The interaction between multiple species on the surface of light-absorbing materials directly impacts the performance of photothermal catalytic process. Based on this, we present the latest perspectives on photothermal CO2 capture and conversion, which focus on (1) the mechanism of functional group-assisted photothermal process, (2) the effects of functional group species, configurations, spatial positions, and surface interactions on photothermal catalytic reactions, and (3) the interaction between substrates and functional groups. Finally, an insightful perspective is drawn in the last section.

Key words: Molecular structure, Photothermal effect, Mass-energy transfer, CO2 capture and conversion
