  author={Bhupendra Kumar and Mark J Llorente and Jesse D. Froehlich and Tram Dang and Aaron J Sathrum and Clifford P Kubiak},
  journal={Annual review of physical chemistry},
The recent literature on photochemical and photoelectrochemical reductions of CO(2) is reviewed. The different methods of achieving light absorption, electron-hole separation, and electrochemical reduction of CO(2) are considered. Energy gap matching for reduction of CO(2) to different products, including CO, formic acid, and methanol, is used to identify the most promising systems. Different approaches to lowering overpotentials and achieving high chemical selectivities by employing catalysts… CONTINUE READING
