Photocatalytic asymmetric C-C coupling for CO₂ reduction on dynamically reconstructed Ru^δ+-O/Ru⁰-O sites.

ABSTRACT: Solar-driven CO₂ reduction to value-added C₂ chemicals is thermodynamically challenging due to multiple complicated steps. The design of active sites and structures for photocatalysts is necessary to improve solar energy efficiency. In this work, atomically dispersed Ru-O sites in Ru_xIn_2-xO₃ are constructed by interior lattice anchoring of Ru. This results in the dynamic reconstruction of Ru^δ+-O/Ru⁰-O sites upon photoexcitation, which facilitates the CO₂ activation, *CO intermediates adsorption, and C-C coupling as demonstrated by varied in situ techniques. A SiO₂ core in Ru_xIn_2-xO₃/SiO₂ construction further enhances the solar energy utilization and
