Abstract: Co3O4 decorated flower-like g-C3N4 hybrid nanocatalysts were successfully synthesized and prepared via a facial hydrothermal method. The composition and morphology of the as-synthesized Co3O4/g-C3N4 nanocatalysts were characterized by the techniques of XRD, FT-IR, SEM, TEM, XPS and N2-sorption. The analysis results indicated that the as-synthesized samples possess the flower-like structure, which consisted of g-C3N4 nanosheets and Co3O4 nanoparticles with the size about 25nm. The as-prepared Co3O4/g-C3N4 catalysts possess high catalytic activity and excellent stability for carbon monoxide (CO) oxidation. The total conversion of Co can be kept for more than 48h under the reaction temperature of 120∘C.
