The catalytic activity of nanocomposite materials with palladium nanoparticles deposited from a colloidal solution on activated carbon, nitrogen-containing carbon nanotubes, graphite, and γ-Al2O3 in the o-nitrotoluene hydrogenation is studied. A significant effect of the carbon support nature on the catalyst activity is found. It is shown that the highest activity is revealed by colloidal palladium. In the case of supports strongly interacting with reaction products, the catalytic activity of supported catalysts significantly reduces.
