Abstract: PdZn stabilized nanoparticles were prepared by polyol method and introduced into the matrix by addition into TiO2 sol in the presence of a template Pluronic F127. The prepared catalyst have been tested in the selective hydrogenation of 2-methyl-3-butyn-2-ol, and the results have been compared with catalysts prepared by conventional impregnation. Nanoparticles stabilized with polyvinylpyrrolidone exhibited good activity (1.1 to 1.8 molMBY/molPd/s-1) and high selectivity to 2-methyl-3-buten-2-ol (81.5-88.9% at 95% conversion). The influence of the kind of the stabilizer, the stabilizer/metal molar ratio and activation conditions on the catalytic behavior of the samples was analyzed. It is shown that the particle size does not significantly affect the catalytic properties in the range of 4.4 to 6.5 nm. The kind and amount of stabilizer seems to be crucial to prepare efficient catalyst
