The energy-intensive desorption stage in CO2 capture often relies on thermal energy, predominantly sourced from fossil fuels. As renewable energy options become increasingly accessible, there is a pressing need for innovations in CO2 capture materials and reactors. This study explores the efficiency of different energy transfer mechanisms in capturing and releasing CO2 from capture materials. Non-thermal energy transfer mechanisms, specifically microwave radiation and electrolysis, are highlighted due to their ability to provide more targeted conditions for the effective release of captured CO2. Nanoscale hybrid materials offer a unique, tunable platform for combining CO2 capture materials with materials designed for enhanced non-thermal energy absorption. The research investigates the CO2 capture and release behaviors of these hybrid materials under various energy transfer mechanisms. Comparative analyses of desorption kinetics are conducted with different nanoscale hybrid materials. Additionally, the study explores the impact of structural parameters on the different energy transfer mechanisms’ CO2 desorption. This comprehensive investigation aims to advance our understanding of CO2 capture and release processes in nanoscale hybrid materials, paving the way for more sustainable carbon capture technologies.
