The synthesis, characterization of highly active and durable new carbon -polymers based nanocomposites and their applicability for new generation alcohol based alternative energy sources

In the last century, the increase in population and the need for energy have been increasing linearly. Today, energy is provided from fossil-based sources, but it is also known that fossil-based resources will beconsumed in the near future. This is why scientists are looking for alternative energy sources. Alternative energy sources can be classified as water energy, thermal energy, solar energy, wind energy and fuel cells. Scientists have been attracted by the ability of fuel cells in alternative energy sources to produce high energy with low amount of fuel. There are a lot of researches about fuel cells and it is thought that fuel cells will be a suitable power source for the future. Fuel batteries are named and classified according to the energy source used in them. The alcohol fuel battery in the fuel cells constitutes this thesis concept and contains catalyst synthesis to develop the anode part. In this thesis, graphene oxide (GO) which is used as carbon support was synthesized by modified Hummer's method and graphene oxide was converted to a reduced graphene oxide (rGO) by the hydrazine hydrate method. Later PANI and reduced graphene oxide were combined to form composite. Finally, PtCl4 salt was added to the support material to perform the reduction and characterization processes. transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), atomic force microscopy (AFM) and Raman spectroscopy (RS) techniques were used to determine the morphological characteristics of the synthesized nanohybride. Cyclic voltammetry (CV) was used to determine the chemical properties and chronoamperometry (CA) techniques were used for stability tests. Also, the particle size measured in XRD and TEM was found to be ± 3.9 nm. In CV the current density was measured as 46.5 mA / cm2.
