In the present study, titanium oxide nanoparticles were used as the support for platinum nanoparticles catalysts. The microstructure and phase characterizations of the synthesized catalysts were performed using field emission scanning electron microscopy (FE-SEM), energy dispersive spectroscopy (EDS), and X-ray diffraction analysis (XRD). The ORR activity and durability of the catalysts were then studied by cyclic voltammograms (CVs) in N2 and O2 saturated 0.1 M HClO4electrolyte and accelerated stability test (AST) using rotating disk electrode (RDE) technique.
