Author:Mathe, Ntombizodwa R; Scriba, Manfred R; Rikhotso, Rirhandzu S; Coville, NJDate:2017Bimetallic Pt–Ni nanoparticles were synthesized for use as electrocatalysts for the methanol oxidation reaction using a cost-effective microwave-irradiation synthesis procedure that offers precise temperature control. By varying the concentration ...Read more
Author:Mkwizu, TS; Modibedi, Remegia M; Mathe, Mahlanyane KDate:May 2011This work will describe our recent advances in room-temperature, sequential electrochemical deposition (in aqueous media) of nanostructured multimetallic systems of variable composition, and morphologies, directly onto carbon supports such ...Read more
Author:Mathe, Mahlanyane K; Mkwizu, TS; Cukrowski, IDate:Nov 2008The paper reports on the development of automated electrochemical deposition method as a synthetic strategy for fabrication of catalytically-active thin-films (or nanostructured) materials, composed of platinum Group Metals (PGMs), with ...Read more
Author:Maphoru, MV; Heveling, J; Kesavan Pillai, SreejaraniDate:Jul 2017Oxidative coupling of naphthols is a useful method for the formation of new carbon-carbon bonds in organic synthesis. In the presence of hydrogen peroxide, platinum supported on activated carbon catalyses this reaction. The outcome is influenced ...Read more
Author:Nxumalo, S; Chikwanda, HK; Machio, Christopher NDate:Oct 2010A TiPt alloy was produced by mechanically alloying the desired quantities of titanium and platinum. The resultant TiPt alloy powder was cold pressed to produce green bodies. Several sintering conditions were used to sinter this alloy. It was ...Read more
Author:Maphoru, MV; Kesavan Pillai, Sreejarani; Heveling, JDate:Apr 2017Compositional and morphological studies on supported platinum are important for the improvement and expanded use of catalysts for oxidative coupling reactions. Nanocomposites consisting of 5% Pt supported on activated carbon and promoted with ...Read more
Author:Nkosi, SS; Mwakikunga, Bonex W; Sideras-Haddad, E; Forbes, ADate:Jun 2013Highly crystalline nanospherical iron–platinum systems were produced by 248 nm laser irradiation of a liquid precursor at different laser fluences, ranging from 100–375 mJ/cm2. The influence of laser intensity on particle size, iron composition, ...Read more
