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.
