BiOCl Atomic Layers with Electrons Enriched Active Sites Exposed for Efficient Photocatalytic CO₂ Overall Splitting.

ABSTRACT: Given the limited exposure of active sites and the retarded separation of photogenerated charge carriers in those developed photocatalysts, photocatalytic CO₂ splitting into value-added chemicals has suffered from the poor activity and remained in great challenge for real application. Herein, hydrothermally synthesized BiOCl with layered structure (BOCNSs) was exfoliated into thickness reduced nanosheets (BOCNSs-w) and even atomic layers (BOCNSs-i) via ultrasonication in water and isopropanol, respectively. In comparison with the pristine BOCNSs, the exfoliated BiOCl, especially BOCNSs-i with atomically layered structure, exhibits much improved photocatalytic activity for CO₂ overall splitting to produce CO and O₂ at a stoichiometric ratio of 2:1, with CO e
