batteries and PV cells, and thin-film organic PV cells. Printable,
electrically conductive gel for potential use in energy storage and biofuel
cells. Nitrogen-doped porous carbon for CO2 capture.
Understanding and controlling surface and interfacial chemistry, and
materials synthesis. Applying this to new materials and processes for next
generation low-cost solar cells, fuel cells and catalysts
Developing materials for heterogeneous catalysis and photocatalysis using
nanoparticles and nanocrystals, especially of titanium dioxide. Applications
include hydrogen and methanol generation through photocatalysis, reduction
of methane emissions, PV solar cells, solid oxide fuel cells and batteries.
Fundamental and applied electrochemistry: solar fuels, fuel cells, and
