In this project, Pt/NiO−GO nanocatalyst is grown on nickel foam (NF) and, its catalytic activity towards electrochemical oxidation of methanol in acidic media is studied. The first step is devoted to the synthesis of NiO−GO support by a hydrothermal method. Then Pt nanoparticles (∼34.3 nm) are electrodeposited on this supporting material. Hydrothermal and electrochemical deposition conditions are optimized. Surface of modified NF was inspected for physical characterization and Chemical composition by some techniques such as field emission scanning electron microscopy (FESEM), energy‐dispersive X‐ray spectra (EDS), and X‐ray diffraction (XRD). In the electrochemical section, the catalytic performance of Pt/NiO−GO/NF towards methanol oxidation is investigated by cyclic voltammetry and chronoamperometry measurements. The electrochemical impedance spectroscopy (EIS) is elected to deliberate charge transfer resistance on the catalyst surface. Mass activity, electrochemical surface area (ECSA) and durability of prepared catalysts are compared with commercial Pt/C. Deliberations prove the superiority of Pt/NiO−GO/NF towards methanol oxidation in acidic media. The Superior quality of synthesized nanocatalyst that is attributed to the synergetic effect of the NiO−GO support material and Pt nanoparticles, indicate that Pt/NiO−GO/NF can be successfully used as the anode in the direct methanol fuel cell (DMFC).

“…Polyelectrocatalyte has been illustrated to show great potential in producing polymer/graphene substrates for noble metal catalysts, since it can induce large amount of surface charge density and fortify the electronic attraction with metal salt precursors [117,118]. As an example, PDDA is a widely used cationic polyelectrolyte and could act as capping ligand to stabilize metal nanocrystals.…”

“…Thus, further modification of the graphene sheet is required in order to increase its efficiency as a catalyst support [13]. Now a particularly attractive option is to functionalize GNs by covalent or non-covalent method with atoms or molecules [14][15][16]. The covalent modification changes the carbon hybridization of graphene from sp 2 to sp 3 and resulted in unwanted alternation or even destruction of the basic electronic properties of graphene [17].…”
