TiO2-based photocatalysts have attracted great interest, with regard to their ability to convert CO2 into hydrocarbons, because of their excellent stability, nontoxicity, and low cost. However, this reaction suffers from low efficiency when TiO2-based materials are used owing to inefficient CO2 capture on the TiO2 surface.

To tackle this problem Can Xue, Nanyang Technological University, Singapore, and co-workers have functionalized TiO2 nanoparticles with amine groups, which substantially facilitate the capture of CO2 for photoconversion. This chemisorption causes more-effective activation of the CO2 and charge transfer from excited TiO2. The result is the enhancement of the photocatalytic rate of CO2 reduction to methane and CO. No decrease in yield was observed after three cycles, suggesting high stability of the TiO2-based catalyst during the photocatalytic process.

The researchers hope that this research will lead to further developments in the area of efficient CO2 capture.
