Abstract :

The influence of varying the stabiliser type (PVA, PVP, and THPC) during the synthesis of palladium nanoparticles via solimmobilisation technique on the resulted particles, and their catalytic activity on the liquid phase transfer dehydrogenation of 1-PhEt has been investigated. The chemical composition and morphology of the fresh and used catalysts were determined using XRD, XPS, BET, SEM-EDX, and TEM. By evaluating the catalytic activity of the series of 1% Pd/TiO2 catalysts prepared using different PVA/Pd weight ratio, the results illustrate that two main parameters can mainly control the catalytic activity of 1% Pd/TiO2 in the liquid phase transfer dehydrogenation of 1-PhEt, these are Pd(0)/Pd(II) ratio and the particle size of the catalyst. The results show that two different regimes can be identified during the liquid phase transfer dehydrogenation of 1-PhEt. At the initial time, the particle size parameter appears to control the catalytic performance of 1-PhEt while the effect of Pd oxidation state starts to take place after reaching iso-conversion, where the percentage of Pd(0)/Pd(II) increases while the reaction proceeds
