英文摘要: One-step production of pyruvic acid through selective oxidation of glycerol was investigated using Received 9 March 2017 lead promoted platinum/activated carbon (Pb-Pt/AC) catalysts under mild conditions. The results Accepted 10 April 2017 of N-2 physisorption, X-ray diffraction, X-ray photoelectron spectroscopy, and high-resolution trans Published 5 May 2017 mission electron microscopy revealed that the alloy phases of PtPb and PtxPb were favorable for pyruvic acid production from glycerol oxidation, whereas the Pb-3(CO3)(2)(OH)(2) and surface Pb-0 species inhibited the glycerol conversion. The loading of Pb and the catalyst preparation method (including impregnation and deposition precipitation) affected the formation of different metal species. Pyruvic acid was obtained at a yield of 18.4% on a 5.0 wt% Pb-5.0 wt% Pt/AC catalyst prepared by co-deposition precipitation method and 500 degrees C argon treatment.
