Dr Mbongiseni Dlamini
Research Associate (with Prof Graham Hutchings)
Overview
Dr Dlamini's research interests focuses on the fundamental understanding of catalyzed reactions relevant to the production of clean transportation fuels, commodity chemicals and the solar-driven remediation of pollutants. This approach involves gaining insight on the metal-support interface, the active sites present in the functional material as well as the reaction mechanism. Typically, the study of conventional catalystic materials is done in parallel with tunable model systems such as carbons etc. See our recent publications for more details.
