My research theme is materials for alternative energies and fuels. The material that we are investigating currently are nanocrystalline cuprous oxide (Cu2O) and iron oxide (Fe2O3). By illuminating the nanocrystalline oxides in water with sunlight, the photon energy can be absorbed by the nanocrystalline oxides and can be converted to electricity.  Our ultimate goal with nanocrystalline Cu2O is to generate hydrogen gas by splitting water (i.e., the production of an environmentally friendly energy source in an environmentally sensible manner) and incorporating greenhouse gas, CO2 into alcohols (CH3OH, CH3CH2OH -- other environmentally sensible production of fuels) at the surface of illuminated Cu2O electrode.  The current goal with nanocrystalline Fe2O3 is to reverse the electron flow direction of the material, so the reduction of H+ and CO2 can be performed on Fe2O3 surface.


Akiko Fillinger received her B.S. in Chemistry in 1995 from Portland State University where she became interested in chemical solar-to-electricity conversion under the guidance of Professor Carl Wamser.  She went on to perform her graduate work at Colorado State University in Fort Collins where she received her Ph.D. in analytical chemistry in 2000.  For her graduate thesis, she studied dye sensitized nanocrystalline TiO2 solar cells with Professor Bruce Parkinson

In 2001 she became a Dreyfus Post-doctoral Fellow in Environmental Chemistry at the Division of Applied Sciences and Engineering at Harvard University in Cambridge, Massachusetts (Professors Steven Wofsy and Scot Martin).  After the post-doc experience, she taught for a year at Grinnell College at Grinnell, Iowa as a visiting assistant professor.  She began teaching at Ithaca College in the fall of 2003, and has since taught Physical Chemistry (Thermodynamics & Kinetics, Quantum Mechanics), Instrumental Analysis, Quantitative Chemistry, Environmental Chemistry and Experimental Chemistry I and V.  She maintains an active research group investigating materials for harvesting solar energy and convert to electricity or catalyze fuel (H2) production as well as monitoring the quality of local well water using ion chromatography as a proxy technique to prepare for a possible hydrofracturing practice in this area.
