Rational design of metal single-site embedded porous graphitic carbon nitride (P-g-C3N4) nanostructures exploiting maximum atom utilization is warranted to enhance the thermal CO oxidation (COOx) reaction. Herein, a facile, green, one-pot, and template-free approach developed fabricate hierarchical P-g-C3N4-crumpled ultrathin nanosheets atomically doped with copper single atoms (Cu-P-g-C3N4). Mechanistically, quick protonation melamine pyridine under acidic conditions induces deamination form melem, which polycondensed heating. The interconnected pores, high surface area (240 m2g-1), maximized exposed isolated Cu atomic active sites (1.8 wt %) coordinated nitrogen P-g-C3N4 are salient features Cu- that endowed complete conversion CO2 at 184 °C. In contrast, only converted 3.8% even 350 °C, implying electronic effect atoms. abundant Cu-nitrogen moieties can drastically weaken binding affinity CO-oxidation intermediates products, thus accelerating reaction kinetics low temperature. This study may promote fabrication various for CO.
