Synthesis of nanocatalysts of graphene oxide/TiO2/Pt and study of its characterization

Polymer Electrolyte Fuel Cell (PEMFCs) convert directly the chemical energy of hydrogen into electrical energy. Graphene is a layer of carbon atoms, connected in a hexagonal 2-D crystalline lattic. Graphene sheets have excellent mechanical, electrical, thermal and optical properties. graphene oxide (GO) is easy to functionalized. In this project, the GO nanosheet were synthesized using the simplified hummers method, The FT-IR results confirmed the existence of oxygen-containing group on the GO nanosheets. Titanium oxosulfate (TiOSO4), and hexachloroplatinic acid (H2PtCl6), were used as the source of titanium and platinum, respectively. TiO2/Graphene oxide catalysts has been successfully prepared with graphene oxide and TiOSO4 in initial reaction, titanium induced by the hydrolysis of TiOSO4 diffused into graphene oxide interlayer with used hydrothermal method and ultrasonic. Pt nanoparticles added to TiO2/GO to study for increase efficiency on the performance proton exchange membrane fuel cell. The structure and composition of the nanocatalyst has been characterized by Xray diffraction, and FT-IR
