| Abstract: | A new method for preparing PtO x -inserted sodium titanate nanotube was reported. By suction of H2PtCl6 ethanol solution into the nanotubes first and annealed at 653 K for 3 h afterwards, Pt nanoparticles formed in the nanotubes. The size of Pt nanoparticles is controlled by the dimensions of nanotubes. Some of them are spherical, some are nanorods. XPS and XRD results revealed that during annealing the following complex reaction happened: $Na_1.1H_0.9Ti_2O_4(OH)_2 + H_2PtCl_6+ O_2 \rightarrow TiO_2(anatase) + PtO_x(x=1,2)+NaCl+ HCl\!\uparrow\!\!.$ |
