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.

Photovoltages for hydrogen-terminated p-Si(111) in an acetonitrile electrolyte were quantified with methyl viologen [1,1′-(CH3)2-4,4′-bipyridinium](PF6)2, abbreviated MV2+, and [Ru(bpy)3](PF6)2, where bpy is 2,2′-bipyridine, that respectively undergo two and three one-electron transfer reductions.
Here, we show that in the presence of pyridinium tetrafluoroborate, [CpW(CO)3]− reacts further to form a metal hydride complex CpW(CO)3H.
