Comparative surface electrochemistry of Co and Co3O4 nanoparticles: nitrite as an analytical probe

Author: Adekunle, AS ; Ozoemena, KI Date: Dec 2010 This study described the decoration of edge plane pyrolytic graphite electrode (EPPGE) with synthesised cobalt and cobalt oxide nanoparticles. The modified electrode was characterised by techniques such as TEM, FESEM, XRD, EDS, cyclic voltammetry ... Read more
Covalently cross-linked polyetheretherketone proton exchange membrane for DMFC

Author: Luo, H ; Vaivars, G ; Modibedi, Remegia M ; Mathe, Mahlanyane K Date: May 2009 The proton exchange membrane was prepared by covalent cross-linking sulfonated-sulfinated polyetheretherketone. The cross-linked membrane showed high proton conductivity (0.04 S/cm) with suitable water uptake, low methanol permeability (2.21 ... Read more
Electrochemical characterization of mixed self-assembled films of water-soluble single-walled carbon nanotube-poly(m-aminobenzene sulfonic acid) and Iron(II) tetrasulfophthalocyanine

Author: Agboola, BO ; Pillay, J ; Makgopa, K ; Ozoemena, KI Date: Sep 2010 The redox activities of water-soluble iron(II) tetrasulfophthalocyanine (FeTSPc) and single-walled carbon nanotube-poly(m-aminobenzene sulfonic acid) (SWCNT-PABS) adsorbed on a gold surface precoated with a self-assembled monolayer (SAM) of ...

Voltammetric and impedimetric properties of nano-scaled -Fe2O3 catalysts supported on multi-walled carbon nanotubes: catalytic detection of dopamine

Author: Adekunle, AS ; Ozoemena, KI Date: Dec 2010 The electron transfer and electrocatalytic proiperties of iron oxide nanoparticle (g-Fe2O3) catalysts supported on MWCNTs are described. The MWCNT-Fe2O3 and its electrodes were successfully characterised with FESEM, HRTEM, XRD, EDX, cyclic ... Read more
