Author:Fashedemi, OO; Julies, B; Ozoemena, KIDate:Jan 2013We 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
Author:Motsoeneng, RG; Modibedi, Remegia M; Mathe, Mahlanyane K; Khotseng, LE; Ozoemena, KIDate:Sep 2015Surface-limited redox replacement reactions using the electrochemical atomic layer deposition (EC-ALD) technique were used to synthesize PdPt bimetallic electrocatalysts on carbon paper substrate. Electrocatalysts having different Pd:Pt ratio ...Read more
