Ru Single Atom Dispersed Cu Nanoparticle with Dual Sites Enables Outstanding Photocatalytic CO Reduction.

Cu-based catalysts are promising candidates for CO reduction owing to the favorable energetics of Cu sites for CO adsorption and transformation. However, CO reduction involving insurmountable activation barriers and various byproducts remains a significant challenge to achieve high activity and selectivity. Herein, a photocatalyst constructed with single-Ru-site-on-Cu-nanoparticle on BiTiO exhibits exceptional activity and selectivity for CO conversion to CO.
