Solid-state supercapacitors based on polyoxometalate-based crystalline materials modified with polyaniline

Abstract

Owing to the rapid advancement of electric energy and energy storage devices, there exists an urgent demand for solid-state supercapacitors that possess high capacitance and safety features. Polyoxometalates (POMs) –...

Three Viologen Compounds Containing Keggin and Mo-Capped Weakley Polyoxometalates: Photo-/Thermo-/Electro-Chromic Studies

“…First, the cyclic voltammetry curves for compounds 1 – 3 were tested (Figure S16). The carbon paste electrode of compounds 1 – 3 have five pairs of redox peaks, which are attributed to the redox processes of the ligands (I–I ‘and II–II’) and POMs (III–III’, IV–IV’, and V–V’), respectively. − Therefore, both POM anions and viologen cation have good electrical activity.…”
