Visible Light-Driven Acetaldehyde Production from CO and HO via Synergistic Vacancies and Atomically Dispersed Cu Sites.

Acetaldehyde (CHCHO) is of great industrial importance and serves as a key intermediate in various organic transformations. Photocatalytic production of acetaldehyde from CO represents a sustainable route compared to conventional oxidation processes. However, current photocatalytic systems often face challenges, including limited product selectivity and dependence on sacrificial reagents.
