The selectivity of Pd/SiC catalysts for the hydrogenation of nitriles with H2 can be turned from primary to secondary amines by modification of NiO nanodots. In the modified catalysts, the NiO nanodots act as reactive sites to consume hydrogen radicals on the Pd surface, and thus prolong the lifetime of an imine intermediate that determines the product selectivity. Under mild conditions (30 °C, atm. H2), Pd/SiC and NiO-Pd/SiC catalysts exhibit high selectivity to primary (94%) and secondary (99%) amines, resp.
