Abstract:The Dawson-type sulfate polyoxometalate (POM) [S2W18O62]4– has successfully
been
entrapped in polypyrrole (PPy) films on glassy carbon electrode (GCE)
surfaces through pyrrole electropolymerization. Films of varying POM
loadings (i.e., thickness) were grown by chronocoulometry. Film-coated
electrodes were then characterized using voltammetry, revealing POM
surface coverages ranging from 1.9 to 11.7 × 10–9 mol·cm–2, and were stable over 100 redox
cycles. Typical film morphology and composition were revealed to … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
