Research Interests

The emphasis of our research is to elucidate the mechanistic and kinetic details of charge transfer processes in nanostructured assemblies with an objective to improve energy conversion efficiencies. Research projects in the following areas are currently being pursued.

  • Nanoparticles and Advanced Materials: Metal and semiconductor nanostructures, Molecular Clusters & Carbon Nanotubes - Synthesis, characterization, and surface functionalization, Optical properties, Photoelectrochemistry; and Sensor applications.
  • Light Energy Conversion: Design of inorganic-organic nanoassemblies for light energy conversion, Organic photovoltaics and quantum dot solar cells
  • Photocatalysis and Hydrogen production: Carbon nanostructures (Carbon nanotubes and fullerenes) and and semiconductor metal composites for photocatalytic hydrogen production
  • Chemical Processes in Heterogeneous Media: Surface photochemical processes, molecular clusters, ultrafast photophysical and photochemical events in oxides and polymers, mechanism and kinetics of photoeffects at semiconductor/electrolyte interface.
  • Environmental Science: advanced oxidation processes for treating organic wastes from water - use of metal oxide semiconductors such as TiO2, SnO2 and ZnO to sense and degrade haloaromatics and azo dyes. Simultaneous sensing and destruction of low level toxic organics.
