Efficient Aerobic Oxidation of Ethyl Lactate to Ethyl Pyruvate over V₂O₅/g-C₃N₄ Catalysts.

ABSTRACT: Graphitic carbon nitride (g-C₃N₄)-supported V₂O₅ catalysts were prepared by the impregnation pyrolysis method, and their physicochemical properties were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared (FT-IR), Raman, X-ray photoelectron spectroscopy (XPS), UV-vis, TGA, N₂ adsorption, and H₂-TPR. These catalysts exhibit extremely high activity and selectivity in the aerobic oxidation of ethyl lactate to ethyl pyruvate. The excellent catalytic performance derives from the high surface-chemisorbed oxygen species. Low calcination temperature and interaction with g-C₃N₄ are conducive to increasing the surface-chemisorbed oxygen species of V₂
