Graphene Nano sheet, is one the critical topics in materials science, which has been extensively studied due to the thermal, mechanical, and chemical properties arising from their strictly 2D structure, also because of the potential technical applications [3ref]. Particularly, these remarkable characteristics enable it to be a promising candidate as a new 2D support to load metal nanoparticles (NPs) for application in fuel cells [2ref]. A high-efficiency energy production without contamination is a major challenge in technology which can be resolved by using the electrochemical conversion of fuel cells [2ref]. In this research, we tried to figure out this challenge by using Methanol, because methanol shows a lower ratio of H/C due to lack of C-C bindings. In addition, it can be deformed at lower temperature in comparison with other organic material [ref]. our anode electro catalyst is designed by chemical synthesis of platinum electrocutes and platinumzirconium oxide in 4:1 ratio on Graphit oxide(GO) and multi-wall carbon nanotubes (MWCNT). Furthermore, NaBH4 used as a reducing agent to provide the anodic electro catalysts in direct methanol fuel cells. To investigate the structural properties, morphology and, electrochemical we characterized our electro-catalysts by X-ray diffraction (XRD), transmission electron microscopy (TEM), and cyclic voltammeter (CV) methods. Our results indicate that the PtZrO2 /GO electro catalyst shows significantly higher flow rate in high initial potentials to compare with what it is reported in the literature.
