Pulse plating of manganese oxide nanoparticles on aligned MWCNT

Abstract

In the present study, aligned multiwalled carbon nanotube (MWCNT) arrays were electrodeposited with manganese oxide as electrode material for capacitor application. The electrode material was prepared in a double-stage process. The first stage, the preparation of the MWCNT array on thin nickel foils by chemical vapour deposition is well known and has already been published. This study has its focus on the second step, the electrodeposition of manganese oxide on MWCNT. Electrodeposition was performed by pulse plating of manganese oxide from a manganese acetate electrolyte. The mechanism and kinetics of this deposition process were electrochemically characterised. Additionally, the manganese oxide modified MWCNT arrays were investigated by scanning electron microscopy and Raman spectroscopy. Furthermore, the capacitor performance and the increase in the capacitance of the modified MWCNT arrays were investigated by cyclic voltammetry in a sodium sulphate electrolyte

Raman and ultraviolet–visible spectroscopy of titanium chromium nitride thin films

“…To date, various spectroscopic researches have been undertaken so as to characterize the features of ceramic and metallic materials [7][8][9][10]. Raman spectroscopy and the acquisition of knowledge regarding the phonon modes aid in possessing a thorough understanding of defining characteristics of the materials [11][12][13][14][15][16].…”

Electrophoretic deposition of carbon nanotubes on aluminium for capacitor application

“…In case of success, the produced EDLC could, in turn, offer the possibility for further modification, wet-in-wet, e.g. by electrophoretic or electrochemical deposition of transition metal oxides or polymers for hybrid capacitor applications [17][18][19].…”
