Comparative electrocatalytic oxidation of ethanol, ethylene glycol and glycerol in alkaline medium at Pd-decorated FeCo@Fe/C core-shell nanocatalysts

Author: Fashedemi, OO ; Ozoemena, KI Date: May 2014 Electrocatalytic 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
Electro-oxidation of ethylene glycol and glycerol at palladium-decorated FeCo@Fe core–shell nanocatalysts for alkaline direct alcohol fuel cells: functionalized MWCNT supports and impact on product selectivity

Author: Fashedemi, OO ; Miller, HA ; Marchionni, A ; Vizza, F ; Ozoemena, KI Date: Apr 2015 Half-cell reactions and alkaline direct ethylene glycol and glycerol fuel cells (DEGFC and DGFC) have been studied on Pd-based ternary core–shell (FeCo@Fe@Pd) nanocatalyst using multi-walled carbon nanotubes bearing carboxylic (MWCNT-COOH) ...

Enhanced methanol oxidation and oxygen reduction reactions on palladium-decorated FeCo@Fe/C core–shell nanocatalysts in alkaline medium

Author: Fashedemi, OO ; Ozoemena, KI Date: Dec 2013 Palladium based nano-alloys are well known for their unique electrocatalytic properties. In this work, a palladium-decorated FeCo@Fe/C core-shell nanocatalyst has been prepared by a new method called microwave-induced top-down nanostructuring ... Read more
A facile approach to the synthesis of hydrophobic iron tetrasulfophthalocyanine (FeTSPc) nano-aggregates on multi-walled carbon nanotubes: A potential electrocatalyst for the detection of dopamine

Author: Fashedemi, OO ; Ozoemena, KI Date: Jul 2011 A facile method has been utilized to synthesize ahydrophobic form of nano-scaled iron (II) tetrasulfophthalocyanine (nanoFeTSPc), integrated with functionalized multi-walled carbon nanotubes (fMWCNT-nanoFeTSPc). The nanocomposite was characterized ... Read more
High-performance symmetric electrochemical capacitor based on graphene foam and nanostructured manganese oxide

Author: Bello, A ; Fashedemi, OO ; Lekitima, JN ; Fabiane, M ; Dodoo-Arhin, D ; Ozoemena, KI ; Gogotsi, Y ; Johnson, ATC ; Manyala, N Date: 2013 We have fabricated a symmetric electrochemical capacitor with high energy and power densities based on a composite of graphene foam (GF) with 80 wt% of manganese oxide (MnO(sub2)) deposited by hydrothermal synthesis. Raman spectroscopy and ... Read more
Oxygen reduction reaction at MWCNT-modified nanoscale iron(II) tetrasulfophthalocyanine: remarkable performance over platinum and tolerance toward methanol in alkaline medium

Author: Fashedemi, OO ; Ozoemena, KI Date: Apr 2015 A nanoscale iron(II) tetrasulfophthalocyanine (nanoFeTSPc) catalyst obtained by co-ordinating with hexadecyltrimethylammonium bromide and subsequently anchored onto multi-walled carbon nanotubes (MWCNTs) for oxygen reduction reaction (ORR) ...

Synthesis of Pd-coated FeCo@Fe/C core-shell nanoparticles: microwave-induced ‘top-down’ nanostructuring and decoration

Author: Fashedemi, OO ; Julies, B ; Ozoemena, KI Date: Jan 2013 We report a novel microwave-induced fast and efficient synthesis of sub-10 nm sized palladium-decorated FeCo@Fe core–shell nanoparticles (ca. 3–7 nm) from a large-sized FeCo@Fe (0.21–1.5 µm) precursor, suggesting ‘top-down’ nanosizing. The ... Read more
