Electro-oxidation of alcohols using carbon supported gold, palladium catalysts in alkaline media

Author: Maumau, Thandiwe R ; Modibedi, Remegia M ; Mathe, Mahlanyane K Date: May 2018 Mono and binary Pd-Au based catalysts were synthesized using the NaBH4 assisted ethylene glycol reduction method. The catalysts were supported on Vulcan XC 72 carbon black and denoted as Pd/C, Au/C, Pd(Au/C) and Pd-Au/C co-reduction. Pd:Au ... Read more
Gold, scorched earth and water: the hydropolitics of Johannesburg

Author: Turton, AR ; Schultz, C ; Buckle, H ; Kgomongoe, M ; Malungani, T ; Drackner, M Date: Jun 2006 Johannesburg is an unusual city because it is one of the few major cities of the world that does not lie on a river, a lake or a seafront. Since the discovery, of gold in 1886, Johannesburg has grown from a dusty mining town to a major urban ... Read more
Mining research for enhanced competitiveness

Author: Vogt, D ; Brink, VZ ; Donovan, S ; Ferreira, G ; Haarhoff, J ; Harper, G ; Stewart, R ; Van Schoor, Michael Date: Nov 2008 Mining is very important to South Africa, contributing 7% of GDP directly, and 15% indirectly and employing more than 450 000 people. With the world’s largest resources of gold, platinum and ferrochrome, and major coal resources, mining will ... Read more
Multistage electrodeposition of supported platinum-based nanostructured systems for electrocatalytic applications

Author: Mkwizu, TS ; Modibedi, Remegia M ; Mathe, Mahlanyane K Date: May 2011 This 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 ...
