Microwave-irradiated synthesis is a new promising technique for the preparation of size-controlled metallic nanostructures. Xu et al. (2010) reported the preparation of Pt nanoparticles supported on CNTs [9]. In this method, solutions of Pt precursor (H2PtCl6. 6H2O), ethylene glycol and KOH are mixed in a vial and CNTs are uniformly dispersed in mixed solution. The closed vial is then placed in a microwave oven (2450 MHz, 800 W) and heated for the required time. The resulting suspension was filtered and dried at 120 °C. This preparation method resulted in Pt nanoparticles on the surface of CNTs having uniform spherical shape with diameter of 15 ± 3 nm.
