We report herein a C₃N₄ templating method for successfully synthesizing defective, porous TiO₂ nanosheets with Pt decoration as an efficient photocatalyst for C₂H₄ oxidation. During the synthetic procedure, C₃N₄ not only acts as a 2D template to direct synthesize porous TiO₂ nanosheets (TiO₂-NS) but also facilitates oxygen vacancy formation on TiO₂. The resultant TiO₂-NS shows enhanced UV and visible-light photoactivities toward C₂H₄ oxidation as compared to blank TiO₂ (TiO₂-B) prepared without C₃N₄ template. Subsquently, Pt nanoparticles are homogeneously decorated onto the surface of TiO₂-NS. The as-obtained Pt-TiO₂-NS exhibits efficient photocatalytic activity and stability toward ethylene oxidation.
