We are seeking a Postdoctoral Research Associate who will support the Geochemistry and Interfacial Sciences Group, Chemical Transformation Section in the Chemical Sciences Division (CSD), Physical Sciences Directorate (PSD) at Oak Ridge National Laboratory (ORNL). The postdoctoral researcher will focus on combined carbon capture and conversion in ionic liquids and aqueous electrolytes.
This position is funded by an Energy Research Frontier Center (EFRC) – the Center for Understanding and controlling Accelerated and Gradual Evolution of Materials for Energy (UNCAGE-ME III). The goal of this research project is to gain a fundamental understanding of how degradation of catalysts during combined capture and conversion of carbon dioxide using ionic liquids and aqueous electrolytes.
Specifically, how the structure of the electrocatalysts and the surface chemistry of CO2 reduction evolves as a function of the nature and concentration of the contaminants in both aqueous electrolytes and ionic liquids; and capture and conversion can be combined in ionic liquids. Approaches include both experimental and computational studies of kinetics and reactivity, spectroscopic identification of surface reactants and mechanisms under in situ and operando conditions.
Under general supervision, the Postdoctoral Research Associate will conduct research in synthesizing Cu-based electrocatalysts, measuring electrochemistry of CO2 reduction, and conducting in situ measurements (atomic force microscopy) for mechanistic understanding of degradation.
