Ultrahigh Photocatalytic CO2 Reduction Efficiency and Selectivity Manipulation by Single-Tungsten-Atom Oxide at the Atomic Step of TiO2

Yibo Feng et al.

Summary: The photocatalytic CO2 reduction reaction is a sustainable route to convert greenhouse gases into chemicals. Inorganic photocatalysts, like titanium dioxide (TiO2), have been extensively studied due to their stability and low cost. However, a more efficient TiO2 photocatalyst without noble metals is desired for CO2 reduction. In this study, a novel strategy of anchoring a single tungsten (W) atom site with oxygen-coordination at the intrinsic steps of TiO2 nanoparticles is developed. This strategy allows for the control of active sites composition, resulting in significantly improved CO2 reduction efficiency and methane selectivity.
