The authors reveal aspects of the formation of platinum nanoparticles and chemical coating of carbon support surfaces when preparing model (0.5%Pt/Sibunite) and industrial (0.5%Pt/Graphite) catalysts for synthesizing hydroxylamine sulfate via the hydrogenation of NO in a solution of H2SO4. It is shown that functionalizing the surfaces of supports with nitrogen-containing groups while depositing platinum ensures not only the dispersion of metal but a strong increase in its selectivity toward hydroxylamine sulfate. It is assumed that maximum selectivity is characteristic of active sites being single atoms or small platinum clusters bound to the nitrogen-containing ligands of a carbon surface.
