Palladium nanoparticles were synthesized in the solid-liquid system of palladium oxide-alcohol by microwave irradiation. They were compared with those produced by a conventional heating method. We also used various alcohol solvents and compared the products obtained. The products contained particles that had diameters of several nanometers. In these measurements, microwave heating produced smaller particles than conventional heating because it provided homogeneous and direct heating. Additionally, Pd/spherical carbon (SC) composite particles could be prepared by the same method. For microwave heating, SC particles can support palladium particles without calcination, which is due to selective heating by microwaves.
