Abstract:

Heterogeneous catalysts form a highly important part of everyday life, ranging from the production of fertiliser enabling the growth of crops that sustain much of the world's population to the production of synthetic fuels. They constitute a key part of the chemical industry and contribute towards substantial economic and environmental benefits. Heterogeneous catalysts are also believed to have an important role to play in a future hydrogen economy, reducing our requirements for fossil fuels. To this end, formic acid has been proposed as a potential hydrogen storage material for small portable

Abstract:

The disproportionation of H₂O₂ to H₂O and molecular O₂ catalyzed by platinum nanocatalysts is technologically very important in several energy conversion technologies, such as steam propellant thrust applications and hydrogen fuel cells. However, the mechanism of H₂O₂ decomposition on platinum has been unresolved for more than 100 years and the kinetics of this reaction were poorly understood. Our goal was to quantify the effect of reaction conditions and catalyst properties on the decomposition of H₂O₂ by platinum nanocatalysts and determine the mechanism and rate-limiting step of the reactio

Abstract:

Developing a fundamental understanding of the interactions between catalytic surfaces and adsorbed molecules is imperative to the rational design of new materials for catalytic, sorption and gas separation applications. Experiments that probed the chemistry at the gas-surface interface were employed through the utilization of in situ infrared spectroscopic measurements in high vacuum conditions to allow for detailed and systematic investigations into adsorption and reactive processes. Specifically, the mechanistic details of propene epoxidation on the surface of nanoparticulate Au supported on

Abstract:

The objective of this work is to present formic acid as a suitable compound to be used in a hydrogen economy. Catalytic decomposition of formic acid at mild conditions is evaluated as a model reaction for hydrogen generation, making emphasis on the productivity, reusability of the catalysts, and quantification of concomitant CO evolved from the reaction. Characterisation of the fresh and used catalysts is performed to study the activity/structure relationship and investigate the possible reasons for its deactivation. Computational calculations are used to support experimental data and correlat

Abstract:

This thesis comprises analysis for two types of catalysis: CO oxidation and N2O decomposition; related by their research in sol-gel catalysis. The CO oxidation work was undertaken on behalf of Servomex plc in order to understand how their catalyst-based sensor (Tfx 1750) worked and why it failed when exposed to coal power station flue streams within its two-year guarantee period. This research will show, by means of many analytical techniques and catalytic tests: 1.

Abstract:

<p> The excessive production of peroxynitrite (ONOO<sup>- </sup>) anion is well-known to play a significant role in numerous diseases including chronic inflammation, Type II Diabetes Mellitus (T2DM), Alzheimer's, and Parkinson's. The highly reactive peroxynitrite (PN) is known to nitrate and oxidize proteins, lipids, and nucleotides thus generating toxicity. Thus, our objective was to design and synthesize complexes that can attenuate the toxic effects of PN in vivo <i>in vivo</i> for pharmacological studies and potential therapeutic strategies.

Abstract:

<p> One of the key contributors to the pathogenesis of various diseases is "nitroxidative stress," a condition caused by the overproduction of peroxynitrite (PN). Redox-active transition metal complexes, which function as PN decomposition catalysts (PNDCs), can redirect oxidative potential of PN and are therefore able to reduce nitroxidative stress. Herein, synthetic methods for making polyfunctional trianionic dipyrromethene (DPM) ligand systems with an X-conjugation site for biomolecule coupling were studied. In addition, derivatives of PNDCs with electron donating groups were synthesized to

Abstract:

Copper (II) oxide on ʏ-alumina sorbents/catalysts generated from the thermolysis of supported copper acetylacetonate complex, have shown potential for the possible removal of SO2and NO in a gas stream. These supported metal complexes were prepared by the non-aqueous impregnation of the catalyst precursor {CU(acac)2} on alumina. Diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) was used to investigate the nature of interaction between the support and the π-electron structure of the complex.

Abstract:

Olefin metathesis is a powerful tool for assembly of carbon-carbon bonds. Amines and related N-donors are problematic functional groups in Ru-catalyzed olefin metathesis - a well- documented, but poorly understood problem. The first part of this thesis focuses on amine-induced deactivation pathways; two of which are described in depth. Alkylidene abstraction, a previously unknown reaction for nitrogen nucleophiles, was observed for smaller and less Bronsted-basic amines. Deprotonation of the metallacyclobutane intermediate formed during catalysis is prominent for highly Bronsted basic or ster

Abstract:

Previous studies involving copper (II) complexed with a dissymmetric Schiff base and imidazole derivatives had identified catalase activity of these complexes towards H2O2. Reactions such as this are of great interest due to the important role of copper-based complexes in biological systems. Our research has been conducted to add to the base of knowledge regarding the efforts of other researchers to investigate copper complexes that exhibit similar reactivity as copper-based proteins towards dioxygen. The copper complex chosen for this study contained a tri-dentate Schiff base adduct which,

Ph.D, Faculty of Science, University of the Witwatersrand, 2011<br>Investigations into methane conversion (both catalytic and non-catalytic) and characterization of the carbon produced for use in high efficiency DCFCs were performed. Under non-catalytic processes, a high methane conversion (> 80%) was achieved at 1200 oC at flow rates of between 10-60 ml/min. Analysis of the carbon using Raman spectroscopy showed that the carbon was highly disordered and the degree of disorder increased with increase in methane flow rate (from aD/aG = 1.54 at 10 ml to aD/aG = 2.24 at 60 ml/min).
