Abstract

Base-free selective oxidation of glycerol has been investigated using trimetallic Au-Pd-Pt nanoparticles supported on titania and their corresponding bimetallic catalysts. Catalysts were prepared by the sol-immobilization method and characterized by means of TEM, UV/Vis spectroscopy, diffuse reflectance infrared fourier transform spectroscopy, X-ray photoelectron spectroscopy, and microwave plasma-atomic emission spectroscopy. It was found that of the bimetallic catalysts, Pd-Pt/TiO₂ was the most active with high selectivity to C₃ products. The addition of Au to this catalyst to form the trimetallic Au-Pd-Pt/TiO₂, resulted in an increase in activity relative to Pd-Pt/TiO₂. The turnover frequency increased from 210 h^-1 with the Pd-Pt/TiO₂ catalyst to378 h ^-1 for the trimetallic Au-Pd-Pt/TiO₂ catalyst with retention of selectivity towards C₃ products. The noble trio: Base-free selective oxidation of glycerol is investigated using trimetallic Au-Pd-Pt nanoparticles supported on titania and their corresponding bimetallic catalysts. Increased activity is observed for the trimetallic Au-Pd-Pt/TiO ₂ catalyst, with retention of selectivity towards C₃ products.
