dc.description.abstractFuel Cells (FCs) are devices that convert chemical energy directly in electrical and thermal energy. There are two disadvantages in the process that difficult the implementation of these new power supply. The fuel, hydrogen, is highly flammable and it is difficult to transport and the catalyst is costly. FCs have been attracting worldwide attention because they are environmental friendly and potential as clean and efficient power source. However, their durability and cost have being identified as important issues in this power supply. The objective of this work is to provide a new material based on incorporation of palladium graphene oxide as catalyst. Graphene Oxide (GO) was synthesized from graphite by the modified Hummers method, in water/alcohol medium. The one-step method to incorporate nanoparticles on this nanomaterial was developed using by electron beam (EB). Additionally, this method also reduces the Graphene Oxide (GO). This nanocomposite were characterized by thermogravimetry (TG), Fourier transform infrared (FT-IR), transmission electron microscopy (TEM), x-rays diffraction (XRD) and its potential for electro catalysis were performed by cyclic voltammetry (CV) and amperometry (CA). The results showed that the incorporation of Pd on reduced GO (rGO) by electron beam was 20-40 % in mass. The process using EB and Pd nanoparticles supported on graphene oxide as a support are an alternative, in substitution of conventional methods to the production of electrodes for fuel cells.pt_BR
