Research Synopsis

Research in the Miller group revolves around transformations relevant to global energy concerns, including the storage of solar energy in chemical fuels, proton-coupled electron transfer reactions, and hydrocarbon transformations. Our approach starts with the design and synthesis of transition metal catalysts, then shifts to examining catalyst performance with a focus on understanding reaction mechanism in order to inform catalyst improvements. Our catalysts feature multifunctional ligands: beyond simply supporting the metal center, the ligands position additional functionality in the secondary coordination sphere of the metal and work in concert with the metal center to enhance key steps in catalytic cycles.

News & Publications

The viability of electrochemical N2 binding and splitting by a molybdenum(III) pincer complex, (pyPNP)MoBr3 (pyPNP = 2,6-bis(tBu2PCH2)-C5H3N)), is established in this work, providing a foundation for a detailed mechanistic study of electrode-driven formation of the nitride complex (pyPNP)Mo(N)Br.

 

Here we report nickel photoelectrocatalysts for H2 evolution, leveraging visible-light-driven photochemical H2 evolution from bis(diphosphine)nickel hydride complexes.
