Bimetallic Pd/Pt nanoparticles were directly decorated on the
networked SnO2 nanowires via the -ray radiolysis. Fig. 5(a) shows
a typical FE-SEM image of bimetallic Pd/Pt-functionalized SnO2
nanowires. It is clear that a great number of nanoparticles were
uniformly formed on the surface of each SnO2 nanowire. The inset
of Fig. 5(a) reveals pristine SnO2 nanowires, which reveal a smooth
