Asymmetric Bi and S Single Atoms Over Porous Single‐Crystal TiO2 for Efficient CO2 Photoreduction to Acetic Acid

Advanced Materials, EarlyView.
Photocatalytic CO2 to acetic acid is achieved over triadic synergy among asymmetric Bi–O4, S–O2 and 3D porous single‐crystal TiO2, harnessed by a selective extraction process. Particularly, the Bi sites lower the energy barrier for CHO* and C─C coupling, and the structure of S─O regulates Bi─O and Ti─O as a strong Lewis base site ((SO2–BiO4)δ−) to ...
