Abstract
The Pd/TiO2 nanoparticles synthesized by onestep flame spray pyrolysis FSP with Pd loadings 05–10 wt showed good catalytic performances in the liquidphase selective hydrogenation of 1heptyne Higher selectivities to 1heptene at complete conversion of 1heptyne were obtained on the FSPderived catalysts compared to the ones prepared by conventional impregnation of palladium on the FSPsynthesized and the commercial P25 TiO2 supports Based on the characterization results from Xray diffraction XRD transmission electron microscopy TEM COpulse chemisorption and Xray photoelectron spectroscopy XPS the improved catalytic properties of Pd/TiO2 were attributed to a stronger interaction/an intimate contact between the very fine Pd particles and the TiO2 support obtained via onestep FSP synthesis
