Biogenic MnO₂nanoparticles derived from aCedrus deodarapine needle extract and their composites with polyaniline/activated charcoal as an electrode material for supercapacitor applications

Abstract

A ternary composite of phytogenic MnO2 nanoparticles with polyaniline (PA) and activated charcoal (AC) was designed and fabricated. The MnO2 nanoparticles were synthesised by a green procedure using the extract...

Ternary Fe3O4/reduced graphene oxide/phytic acid doped polyaniline hybrid based supercapacitive electrode with high capacitance retention and good cycling stability

“…Meanwhile, in the low-frequency region, the slope angle of the linear part of F-RGO-p-PANI-II was closer to 901, disclosing the most ideal capacitive performance. 53 To interpret the performance of the hybrids from a kinetic point of view, the dependence of peak current density (i p ) and corresponding scan rate (v) is described according to the eqn (7):…”

“…Green energy storage devices ( e.g. , lithium-ion batteries, 1,2 fuel cells, 3,4 supercapacitors (SCs), 5–7 etc. ) have been widely investigated to address the existing global energy crisis.…”
