Requisition Id 5829
We are seeking a Postdoctoral Research Associate who will focus on measuring and analyzing reaction kinetics and mechanisms of surface chemistry relevant to the catalytic conversions of alkanes and oxygenates. This position resides in the Surface Chemistry and Catalysis (SCC) Group in the Chemical Transformation Section, Chemical Science Division, Physical Science Directorate at Oak Ridge National Laboratory (ORNL).
Under general supervision, the Postdoctoral Research Associate will conduct research on conversion of small oxygenates and possibly alkanes with the goal of correlating surface reactions with surface properties of complex oxides and supported metals. The incumbent will work in close collaboration with other researchers involved in a Basic Energy Sciences (BES) funded project on Fundamentals of Catalysis and Chemical Transformation. The SCC group conducts research on catalytic conversion of oxygenates and alkanes over heterogeneous catalysts, with focus oncomplex oxide catalysts and supported metal catalysts. Primary research interests are focused on mechanistic understanding of coupling reactions, deoxygenation reactions, dehydration reactions, and dehydrogenation reactions, with the goal to reveal the fundamental properties of oxide surface and metal to metal oxide interfaces that control the reaction pathways. The overall approach includes experimental and computational studies of kinetics and reactivity, spectroscopic identification of surface reactants under in situ and operando conditions, and synthesis of model catalysts as an approach to understanding structure-function relationships in catalysis. Arrays of techniques for characterizing physical and catalytic properties are in place or are currently being developed within the group. This research program also takes advantage of resources at ORNL and in particular at the Center for Nanophase Materials Sciences and neutron scattering at the Spallation Neutron Source. The environment at ORNL is highly collaborative and crosscutting research exists between the Chemical Sciences Division and other Divisions at ORNL.
