Some new bimetallic nickel and palladium complexes for catalysis applications
(University of the Western Cape, 2015)
This thesis reports on the syntheses of new bimetallic iminopyridyl nickel(II) and
palladium(II) complexes as catalyst precursors for ethylene ligomerization/polymerization. Tetrahydrophenyl-linked iminopyridyl ligands, ...
Synthesis and characterization of pyridyl/quinolyl imine ruthenium(II) and palladium (II) complexes in catalysis
(University of the Western Cape, 2015)
We report the successful syntheses of a family of tetradentate N-donor pyridyl and quinolyl-imine ligands N1,N2-bis((pyridin-2-yl)methylene)ethane-1,2-diamine (L1), N1,N3- bis(pyridin-2-ylmethylene)propane-1,3-diamine (L2), ...
Supported metal catalysts for friedel-crafts alkylation
(2013)
The research focused on the synthesis, characterisation and activity of zeolite supported metal catalysts for the Friedel-Crafts alkylation of benzene with t-butyl chloride. Alkyl benzenes are traditionally produced via ...
Pyridine carboxamide and pyrazole palladium(II) complexes as catalyst precursors for phenylacetylene polymerization
(University of the Western Cape, 2005)
The objectives of this project were to synthesize and characterise pyridine carboxamide ligands and their palladium complexes and investigate their catalytic activity in the polymerization process of phenylactylene.
Metal complexes based on monomeric and dendrimeric pyrrole-imine ligands as catalytic precursors
(University of the Western Cape, 2007)
Over the recent past, organometallic chemistry has grown and the impact of catalytic applications in various chemical technologies has rapidly evolved from the realm of academic laboratories into full-scale industrial ...
Treatment of brines using commercial zeolites and zeolites synthesized from fly ash derivative
(University of the Western Cape, 2008)
The objectives of this project was to ameroliate two waste materials, namely Acid Mine Drainage and Fly Ash and recover the solid residues for conversion into an adsorbent to treat brine. The solid residues were then ...
Synthesis and characterization of micro- and mesoporous materials for low temperature selective catalytic reduction of nitrogen oxides
(University of the Western Cape, 2011)
In summary, it has been shown during this study that bimetallic Fe and Mn containing catalysts can be prepared by wet impregnation and not by ion exchange because of the competition between two different metals at different ...
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 ...
The catalytic membrane reactor for the conversion of methane to methanol and formaldehyde under mild conditions
(University of the Western Cape, 2005)
This thesis described the development of new catalytic system for the conversion of natural gas (methane) to liquid products such as methanol and formaldehyde. This technology can allow the exploitation of small and medium ...
