When nanoparticles are deposited evenly over the surface of carrier particle size and their distribution by size when printed unchanged. Obtained a series of samples coated with colloidal solution of nanoparticles of palladium on carbon carriers, namely, in graphite, charcoal SCT and the nitrogen-containing carbon nanotubes. The method of TEM shows that the amount of palladium nanoparticles and their size distribution are not changed in their application. The catalytic activity of the samples coated with palladium nanoparticles and colloidal solution of nanoparticles was investigated in the hydrogenation reaction by-nitrotoluolu. Most active palladium colloid characterized in while applying palladium on carbon carriers leads to a decrease in its activity. The lowest activity characterized sample 1% Pd / N-CNT, while the activity of 1% Pd / Graphite comparable with the commercial model Activity 1% Pd / SCT takes an intermediate value. Reduced activity after application palladium may be due to partial blocking of the surface of the metal in the metal carrier. Also, the data indicate a significant influence of the nature and structure of the carbon carrier paladiyvmisnyh the activity of catalysts. Thus it is shown that the activity of commercial catalyst activity exceeds 10% Pd / C in terms of the mass of metal.
