| Research Abstract |
In this study, carbon-supported platinum catalysts with controlled morphologies have been synthesized by spray-drying followed by impregnation of platinum nanoparticles. The electrocatalytic activity of the developed catalyst shows 1.55 times higher than the commercial one. Furthermore, platinum doped tungsten oxide nanocatalysts with a nanorod morphology were prepared using flame spray pyrolysis method. A low Pt concentration (0.12 wt%) was required for optimal photocatalytic activity.
