Effect of P on the electrochemical activity of carbon supported Pt-Ru alloy catalyst for methanol oxidation.

Author: Mohlala, M ; Modibedi, Remegia M ; Mathe, Mahlanyane K Date: Nov 2007 In polymer electrolyte membrane fuel cell (PEMFC), platinum is recognized to be the most active metal for methanol oxidation, however there is a strong CO adsorption tendency, which blocks the surface for further methanol adsorption and leads ...

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 ...

Nanosized ruthenium particles decorated carbon nanofibers as active catalysts for the oxidation of p-cymene by molecular oxygen

Author: Makgwane, Peter R ; Ray, Suprakas S Date: Jul 2013 Highly dispersed, nanosized ruthenium (Ru) particles anchored on carbon nanofibers (CNFs) with varying Ru loadings (1–7 wt.%) showed effective catalytic activity in the aerobic oxidation of p-cymene using molecular oxygen. The activity of the ... Read more
