Ramulifho, Tendamudzimu; Ozoemena, Kenneth I.; Modibedi, Remegia M.; Jafta, Charl Jeremy; Mathe, Mkhulu K. (Elsevier, 2013-03)Electrocatalytic oxidation of ethylene glycol (EG) in alkaline medium using nano-scaled palladium-based bimetallic catalysts (PdM, where M = Ni and Sn) supported on sulfonated multi-walled carbon nanotubes (SF-MWCNTs) ...

Nwanya, Chinwe A.; Jafta, Charl Jeremy; Ejikeme, Paul Madus; Ugwuoke, Paulinus E.; Reddy, M.V.; Osuji, Rose U.; Ozoemena, Kenneth I.; Ezema, Fabian I. (Elsevier, 2014-05)Polyanine and its nanocomposite WO3/PANI films were deposited on fluorine doped tin oxide (FTO) glassslides by simple chemical bath deposition method. The morphology structure of the composite film wasstudied using atomic ...

Makgopa, Katlego; Ejikeme, Paul Madus; Jafta, Charl Jeremy; Raju, Kumar; Zeiger, Marco; Presser, Volker; Ozoemena, Kenneth I. (Royal Society of Chemistry, 2015-02)We present a study on the pseudocapacitive properties of birnessite-type MnO2 grafted on highly graphitized onion-like carbon (OLC/MnO2). In a three-electrode setup, we evaluated two different substrates, namely a platinum ...
