Abstract:
The severe corrosion of carbon supports in harsh fuel cell conditions has attracted the development of ceramic-based catalyst supports. Platinum nanoparticles supported on the carbon nanodots (CNDs)-Titania (TiO2) composite were synthesized in three steps: Firstly, an inorganic support, titania (TiO2) was synthesized by a hydrolysis method. Secondly, the (CNDs-Titania) nanocomposite support was prepared by sonicating pre-synthesized carbon nanodots (CNDs) and TiO2 in equal volumes of ethylene glycol/water solution. Lastly, nanosized Pt particles were deposited onto the CNDs-Titania composite by a polyol method to form a platinum/(CNDs-Titania nanocatalyst. X-ray photoelectron spectroscopy (XPS), transmission electron microscope (TEM), and X-ray difractommetry (XRD) were used to study surface morphology of the synthesized materials. Platinum loading onto the (CNDs-Titania) composite support was quantified by ICP-OES. The electrooxidation of alcohol fuels was investigated in acidic electrolytes using chronoamperometric and voltammetric techniques.
