Author:Mathe, Mahlanyane K; Modibedi, Remegia MDate:Aug 2011Carbon supported Pd-Ni and Pd-Ru-Ni nanocatalysts were prepared by the chemical reduction method, using sodium borohydride and ethylene glycol mixture as the reducing agent. The catalytic activity towards ethanol electro-oxidation in alkaline ...Read more
Author:Fashedemi, OO; Ozoemena, KIDate:May 2014Electrocatalytic oxidation of alcohols in alkaline solutions is critical for the development of direct alkaline alcohol fuel cells (DAAFCs). This work investigated alcohol oxidation reaction (AOR) at a novel palladium-based core-shell nano ...Read more
Author:Ramulifho, T; Ozoemena, KI; Modibedi, Remegia M; Jafta, CJ; Mathe, Mahlanyane KDate:Jan 2012The preparation of metal nanoparticles (Pd, Ni, Sn) supported on sulfonated multi-walled carbon nanotubes (SF-MWCNTs) using a very rapid microwave-assisted solvothermal strategy has been described. Electrocatalytic behaviour of the SF-MWCNT-Pd ...Read more
Author:Rohwer, Mark B; Modibedi, Remegia M; Ozoemena, KIDate:Feb 2015The impact of microwave irradiation on the structure and electrochemistry of monodispersed palladium nanoparticles is reported for the first time. When compared to the Pd that was not subjected to microwave treatment, the microwaved Pd ...Read more
