Dehydrogenation of alkanes using sulfided metal catalysts
(University of Western Cape, 2021)
Light olefins are some of the main raw materials for the petrochemical industry. With the rise in oil prices and increasing demand for olefins, there is an increasing interest in finding cheaper alternatives for processes ...
Determination of paracetamol at the electrochemically reduced graphene oxide-metal nanocomposite modified pencil graphite (ERGO-MC-PGE) electrode using adsorptive stripping differential pulse voltammetry
(University of Western Cape, 2020)
This project focuses on the development of simple, highly sensitive, accurate, and low cost electrochemical sensors based on the modification of pencil graphite electrodes by the electrochemical reduction of graphene ...
Synthesis of binary and ternary Pd-based Nanocatalysts for alcohol oxidation in alkaline media for fuel cell application
(University of the Western Cape, 2020)
This study explores the use of UV-assisted reduction method to synthesise the catalysts, aiming at reducing synthesis time. The Pd and Au catalyst loading is kept at 5 wt% in order to reduce the cost associated with high ...
Microwave synthesis of the Schiff base metal-ligand complexes with Cu and Ni centres
(University of Western Cape, 2021)
Nitric oxide (NO) plays a vital role as a biological messenger in biological systems. However, NO detection and quantification have always posed significant complications. There is, therefore, a need to develop new materials ...
Chemical isolation and electro-chemical characterization of antidiabetic compounds from selected South African lamiaceae plant species
(University of the Western Cape, 2020)
Diabetes mellitus (DM), being one of the most common metabolic disorders with an elevated morbidity and mortality rate around the world. It is characterised by deficiency in insulin secretion or degradation of secreted ...
Membrane module development for water recovery from humid gas
(University of the Western Cape, 2020)
Over the past 5 years, South Africa has been experiencing a severe drought. This has caused industrial and agricultural processes, to compete for a limited supply of water. Since the economy relies mostly on agricultural ...
Coal fly ash and acid mine drainage based heterogeneous Fe catalysts Friedel-Crafts alkylation reaction
(University of Western Cape, 2020)
The catalytic support materials used in the present study are zeolite HBEA and MCM-41. These high silica zeolites were synthesised from coal fly ash (CFA) waste via a novel approach that involved a fusion step, acid assisted ...
Electrochemistry and photophysics of carbon nanodots-decorated nigs(Ni(In, Ga)Se2) quantum dots
(university of western cape, 2020)
Currently, non-renewable sources are mostly used to meet the ever-growing demand for energy. However, these sources are not sustainable. In addition to these energy sources being not sustainable, they are bad for the ...
Development of a bipolar nickel-iron battery prototype for energy storage
(University of Western Cape, 2021)
Energy storage systems represent a viable option to integrate renewable energy sources into the grid network. Multiple energy storage technologies are available such as mechanical, electrical, thermal, and electrochemical ...
Development of nanostructured electrocatalysts using electrochemical atomic layer deposition technique for the direct liquid fuel cells By
(University of Western Cape, 2020)
The depletion of fossil fuel resources such as coal and the concern of climatic change arising from the emission of greenhouse gases (GHG) and global warming [1] lead to the identification of the 'hydrogen economy' as one ...
