Efficient CO2 Capture and Photoreduction by Amine-Functionalized TiO2.

Amine-functionalization of TiO₂ nanoparticles, through a solvothermal approach, substantially increases the affinity of CO₂ on TiO₂ surfaces through chemisorption. This chemisorption allows for more effective activation of CO₂ and charge transfer from excited TiO₂, and significantly enhances the photocatalytic rate of CO₂ reduction into methane and CO.
