Abstract: It was shown that a catalyst obtained by depositing palladium nanoparticles from a colloidal solution onto a carbon support stabilized with polyvinylpyrrolidone exhibits higher activity in liquid-phase hydrogenation of o-nitrotoluene than a commercial sample of Pd/C with the same palladium content. From analysis of data from TEM, XRD, and XPS it was concluded that the increase of activity is due to the increased content of Pd0 in the synthesized catalyst.
