Unlocking bimetallic active sites via a desalination strategy for photocatalytic reduction of atmospheric carbon dioxide.

ABSTRACT: Ultrathin two-dimensional (2D) metal oxyhalides exhibit outstanding photocatalytic properties with unique electronic and interfacial structures. Compared with monometallic oxyhalides, bimetallic oxyhalides are less explored. In this work, we have developed a novel top-down wet-chemistry desalination approach to remove the alkali-halide salt layer within the complicated precursor bulk structural matrix Pb_0.6Bi_1.4Cs_0.6O₂Cl₂, and successfully fabricate a new 2D ultrathin bimetallic oxyhalide Pb_0.6Bi_1.4O₂Cl_1.4. The unlocked larger surface area, rich bimetallic active sites, and faster carrier dynamics within Pb_0.6Bi_1.4O₂Cl_1.4 layers significantly enhanc
