摘要: Abstract Pt/Au/WO3 bimetallic catalysts were prepared by impregnation of Pt onto preformed Au/WO3, obtained a hexadecyl trmethyl ammonium bromide (CTAB)-assisted one-pot synthesis method. The resulting exhibited remarkable synergistic effects for selective hydrogenolysis glycerol to 1,3-propanediol. characterization results showed that doping Au promoted the reduction both and W at low temperatures uniform dispersion on WO3 support. Furthermore, more low-valence species produced surface after introduction Au. These changes in electronic properties resulted enhancement conversion selectivity
