We investigated the catalytic properties of gold nanoparticles deposited on various kinds of supports for solvent-free aerobic oxidation of alkane, oxidation of amine, hydrogenation of imine, and the N-alkylation of primary amine to produce secondary amine. We found that supported gold catalysts exhibited high catalytic activity and product selectivity when gold nanoparticles and clusters were deposited on suitable supports for each reactions.We also found that metal oxide without gold could catalyze the ammoxidation of alcohol to yield nitrile with high selectivity.
