Abstract: Palladium nanoparticles stabilized by poly (N-vinyl-2-pyrrolidone) (PVP) can be synthesized by corresponding Pd(acac)2(acac = acetylacetonate) as precursor in methanol at 80°C for 2 h followed by reduction with NaBH4and immobilized onto SiO2prepared by sol-gel process under acidic conditions (HF or HCl). The PVP/Pd molar ratio is set to 6. The effect of the sol-gel catalyst on the silica morphology and texture and on Pd(0) content was investigated. The catalysts prepared (ca.2% Pd(0)/SiO2/HF andca.0,3% Pd(0)/S…
