 research interests

  • Green technologies for the production of hydrogen gas, with particular emphasis on photo-electrochemical systems, which use solar energy to split water into hydrogen and oxygen. Hydrogen produced renewably, could be used to decarbonise power sources, manage intermittency of renewable power sources and smooth the dynamics of electrical power demands;
  • Aquoues and gaseous CO2 reduction to fuels;
  • 3D printing of functional materials for electrochemical and photo-electrochemical applications;
  • Metal recovery from plating wastewater by electrodeposition. Metal electrodeposition allows the simultaneous de-contamination of wastewater solutions from toxic metals and the reclamation of the metal in elemental form. The benefit of the latter increases with the market value of the material, as the specific electrical energy consumption of the reclamation process is often substantially smaller than the market price. My particular expertise is in the recovery of nickel but the electrodeposition strategy may be adopted to other metals.
