Polyacrylic acid and polyvinylpyrrolidone stabilised ternary nanoalloys of platinum group metals for the electrochemical production of hydrogen from ammonia
(University of the Western Cape, 2016)
The electrochemical oxidation of ammonia has attracted much attention as an efficient green method for application in direct ammonia fuel cells (DAFCs) and the production of high purity hydrogen. However, the insufficient ...
Electrochemical characterization of platinum based catalysts for fuel cell applications
(University of the Western Cape, 2012)
Fuel cells convert chemical energy from a fuel into electricity through chemical reaction with oxygen. This possesses some challenges like slow oxygen reduction reaction (ORR),
overpotential, and methanol fuel cross over ...
Synthesis, characterization and physicochemical properties of platinum naboparticles on ordered mesoporous carbon
(University of the Western Cape, 2011)
In this study SBA-15 mesoporous silica template was synthesized and used as a sacrificial template in the preparation of ordered mesoporous carbon material. A chemical vapour deposition (CVD) technique using LPG or ...
Platinum based catalysts for the cathode of proton exchange membrane fuel cells
(University of the Western Cape, 2018)
Oxygen reduction reaction (ORR) is carried out in the cathode of the proton exchange membrane fuel cell (PEMFC) and it is known for its sluggish kinetics and the existence of two-pathway mechanism, related with the production ...
Synthesis and characterization of cathode catalysts for use in direct methanol fuels cells
(University of the Western Cape, 2010)
In this work a modified polyol method was developed to synthesize in-house
catalysts. The method was modified for maximum delivery of product and proved to be quick and efficient as well as cost effective. The series of ...
Catalyst Coated Membranes (CCMs) for polymerelectrolyte Membrane (PEM) fuel cells
(University of the Western Cape, 2010)
The main objective of this work it to produce membrane electrode assemblies (MEAs) that have improved performance over MEAs produced by the conventional manner, by producing highly efficient, electroactive, uniform catalyst ...
