Supported Au single atoms and nanoparticles on MoS₂ for highly selective CO₂-to-CH₃COOH photoreduction.

ABSTRACT: Effectively controlling the selective conversion of CO₂ photoreduction to C₂ products presents a significant challenge. Here, we develop a heterojunction photocatalyst by controllably implanting Au nanoparticles and single atoms into unsaturated Mo atoms of edge-rich MoS₂, denoted as Au_n/Au₁-CMS. Photoreduction of CO₂ results in the production of CH₃COOH with a selectivity of 86.4%, which represents a 6.4-fold increase compared to samples lacking single atoms, and the overall selectivity for C₂ products is 95.1%. Furthermore, the yield of CH₃COOH is 22.4 times higher compared to samples containing single atoms and without nanoparticles. Optical experiments demonstrate that the single atoms do
