Shape-Controlled Synthesis and Catalytic Behavior of Supported Platinum Nanoparticles Selective hydrogenation reaction is influenced by many factors, which include the presence of catalytic activators or poisons, the temperature, pressure, solvent agitation and other conditions specific to the particular process. One of the more important considerations for improving selectivity is the steric and electronic circumstance around the metal center. Comparing to inorganic precious metal salts, organo-precious metal compounds with different coordinative ligands provide the special capacity for extensive changes of the steric and electronic circumstance around metal center. This paper provides one method to prepare Pd/C catalyst using organic-platinum compounds as precursor. In the resulted Pt/C catalyst platinum particles are uniform with size around 20 nm and most of them in cubic shape . This Pd/C catalyst show high selectivity (> 99%) in hydrogenation of halonitro aromatic compounds.
