Catalysis, Nanomaterials, Dynamic In-situ Electron Microscopy Developments for visualising and analysing gas molecule-catalyst reactions at the single atom level

Our current research programmes are in the following areas:

  • Heterogeneous Catalysis
  • Development of novel aberration-corrected in-situ environmental electron microscope instrumentation  to visulaise and analyse single atom interactions in gas molecule-solid catalyst surface processes in real-time
  • Novel nanocatalysts for fuel cells; hydrogenation and pollution control
  • Novel nanocatalysts and fundamental understanding of atomic processes in Fischer-Tropsch (FT) processes in energy production
  • Nanomaterials and Interface transitions at the atomic level
  • Economical heterogeneous routes for medicines

Collaborators (including on in-situ studies): Professor E D Boyes, Drs. K Yoshida, A La Grow, M R Ward, D C Lloyd and UK Chemical and Healthcare Industries.
