AB  - In this study, nanocomposites were formed together withKeggin-type K7-xNaxPW11O39∙14H2O(POTs) clustersand oxygenated-graphene (Oxy-G). It was produced as a multilayer bylayer-by-layer self-assembly method using protonated poly (ethylenimine) (PEI).The produced (PEI / POTs / Oxy-G) n multilayer films were controlled by XRD,cyclic voltammetry and UV-visible spectroscopy. (PEI / POTs / Oxy-G) nmultilayers modified on a glassy carbon electrode and the hydrogen evolutionreaction taking advantage of the electrocatalytic activity of thisnanocomposite. Multilayer has been shown to exhibit a potentially goodelectrocatalytic activity at -0.4 V. A notable electrocatalytic hydrogenevolution reaction could be identified on the (PEI/ POTs/Oxy-G)n multilayer.We demonstrate that expanded the application of POTs/G nanocomposites to theelectrocatalysis of oxygen reduction reaction and hydrogen evolution reaction.This excellent approach will offer new insights into different electrode structureand the development of novel electroactive catalysts.
