Research

The Roodt Group focuses on Fundamental and Applied Coordination Chemistry and the integrated investigation of Reaction Mechanisms through the use of crystallography, spectroscopy, computational chemistry, and in particular advanced reaction kinetics.

Four research thrusts probe the applications to:

(i) medicine (radiopharmaceutical and chemotherapeutic models; since 1990`s);

(ii) industrial reactions/homogeneous catalysis/applied process chemistry (since mid 1990`s);

(iii) the development of metal beneficiation technology (since 2007);

(iv) coordination chemistry in the environment (since 2010): special focus on carbon dioxide utilisation and hydrogen generation via solar techniques (since 2016).

The research on medical aspects of pharmaceutical model compounds is in collaboration with Prof Roger Alberto (University of Zurich, Switzerland), Dr Marija Zbacnik (University of Zagreb, Croatia), Dr Gerdus Kemp (PETLaboratories and Klydon, SA), and Prof Ted E Kroon (Physics, University of the Free State, SA). Similarly, the group’s research on model homogeneous catalysts are in collaboration with Profs Vadim Kukushkin and Vadim Boyarsky from the State University of Saint Petersburg, Russia and Dr Esna du Plessis (SASOL). On metal beneficiation the focus is with Dr. Johann Nel from NECSA and for carbon dioxide and water splitting the collaboration is again with Prof Roger Alberto from Zurich, Switzerland.
