Research Interests

Inorganic Spectroscopy and Solar Energy Conversion


Research Synopsis

Research in the Dempsey group applies the tools of physical inorganic chemistry to address challenges associated with developing efficient solar energy conversion processes. In particular, we focus on understanding the proton-coupled electron transfer reactions that underpin fuel production and elucidating electron transfer processes across materials interfaces.

Our research program bridges molecular and materials chemistry and relies heavily on methods of physical inorganic chemistry, including electrochemistry and time-resolved optical spectroscopy.

News & Publications

The ligand-to-metal charge transfer (LMCT) transitions of [Re(dmpe)3]2+ (dmpe = bis-1,2-(dimethylphosphino)ethane) were interrogated using UV/Vis absorbance spectroscopy, photoluminescence spectroscopy, and time-dependent density functional theory.

 

Mesoporous anatase TiO2, mixed anatase/brookite TiO2, and rutile-type SnO2 nanocrystalline films were coated with ultrathin (<5 nm) TiOx by the atomic layer deposition (ALD) of tetrakisdimethylamidotitanium(IV) and water at 150 °C to fabricate SnO2/TiOx and TiO2/TiOx core/shell materials.
