Lowering the parasitic energy demand of CO2 capture technologies is a basic and technical challenge. Using alternative energy sources could reduce energycosts both by lowering the energy required for regeneration and by replacing parasitic energy with renewable sources. Here we report the use of actinic light for the photo-thermal regeneration of CO2 from capture solutions containing nanoparticles. We demonstrate an enhanced regeneration of CO2 due to addition of carbon black nanoparticles. CO2 regeneration efficiency increased with higher nanoparticle concentration and higher initial solution temperatures.
