Inorganic Research

Inorganic chemistry is a discipline that spans areas ranging from materials chemistry to organic synthesis and on to broad problems in energy. The Inorganic Division at the University of North Carolina ranks among the top ten nationally and has been a major strength of the Chemistry Department for decades.

Graduate students in the Inorganic Division are exposed to an exciting research environment, cutting-edge characterization and catalysis facilities, an exciting educational curriculum, and a collegial mentoring environment, all of which together provide an excellent foundation for future careers in industry and academia.

The Inorganic Division is deeply involved in several overarching departmental themes. Catalysis is a particularly prominent research area at UNC, with ongoing activities involving the synthesis of complexes for a broad range of homogeneous catalysis applications – energy, biomass remediation, small molecule synthesis, site-selective activation, asymmetric catalysis, and polymerization – and the exploitation of transition metal complexes in photocatalytic water splitting and carbon dioxide reduction and for applications in biotechnology.

Functional materials chemistry is another strength at UNC, with highly visible research activities in solar fuels, nanoparticles/quantum dots, and photovoltaics.

Recent Research Results

The ligand-to-metal charge transfer excited state of [Re(dmpe)3]2+

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.

Understanding Terminal versus Bridging End-on N2 Coordination in Transition Metal Complexes

Here we elucidate the fundamental factors controlling the two binding modes and determining which is favored for a given metal–ligand system, using both quantitative density functional theory (DFT) and qualitative molecular orbital (MO) analyses.

Interfacial Electron Transfer through Ultrathin ALD TiOx Layers: A Comparative Study of TiO2/TiOx and SnO2/TiOx Core/Shell Nanocrystals

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.
