Chemistry Seminar Series 291 (10/26/18)

October 26, 2018 - 3:00pm

Laura Gagliardi, University of Minnesota

Abstract:

We employ computational modelingl to understand the activity of metal catalysts supported on Zr6 nodes in metal-organic frameworks (MOFs) for reactions related to natural gas conversion, like catalytic oligomerization of abundant C 1, C2, and C3 hydrocarbons to longer congeners or selective oxidation to alcohols or other fuel molecules, while avoiding overoxidation to water and carbon dioxide. For Ni and Co,2 computational studies provide important insights with respect to the catalytic mechanism(s) for observed ethylene dimerization after metal-decoration of the MOF NU-1000. A library of transition metals (TMs), ranging from first row TMs to noble metals, is now being screened computationally to search for optimal catalysts, and structure-function relationships are beginning to emerge from this theory-driven approach.
