Abstract

In this study, nanocomposites were formed together with Keggin-type K7-xNaxPW11O39∙14H2O (POTs) clusters and oxygenated-graphene (Oxy-G). It was produced as a multilayer by layer-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) n multilayers modified on a glassy carbon electrode and the hydrogen evolution reaction taking advantage of the electrocatalytic activity of this nanocomposite. Multilayer has been shown to exhibit a potentially good electrocatalytic activity at -0.4 V. A notable electrocatalytic hydrogen evolution reaction could be identified on the (PEI/ POTs/Oxy-G)n multilayer. We demonstrate that expanded the application of POTs/G nanocomposites to the electrocatalysis of oxygen reduction reaction and hydrogen evolution reaction. This excellent approach will offer new insights into different electrode structure and the development of novel electroactive catalysts.
