BSB 106

Advanced Electrocatalytic Materials for Chemical Conversion and Energy Storage. The primary focus our research effort is fundamental studies of electrochemical reactions, electrocatalyst function and the design of new materials for improving the efficiency of electrical storage and conversion devices such as batteries and fuel cells. Our lab is multidisciplinary, combining electrochemical, analytical, materials and physical chemistry techniques.


My research group is focused on understanding the fundamental reaction steps involved in electrochemical conversion and storage systems.  Specifically, we are interested in the relationship between surface properties that influence the electrocatalytic processes of O2 and CO2 reduction, and the chemical processes governing capacity fade in high capacity Li intermetallic anodes.  For this seminar, I will focus on our recent developed analytical methods to decouple electrochemical processes.  In particular, I will discuss In situ NDP, derivative operando (dOp) NMR methods to to identify reaction intermediate, preferential Li nucleation, trapping and transport in energy storage materials.


Anne Co is an Associate Professor of Chemistry and Biochemistry and an Associate Fellow of the Center for Automotive Research at the Ohio State University.  She received her Ph.D. in Chemistry with a specialization in Electrochemistry from the University of Calgary, Canada.  She then joined the National Research Council Canada’s Institute for Chemical Process and Environmental Technology (NRC-ICPET) as a NSERC Visiting Fellow and later promoted to Research Associate.  In 2008, she was awarded a Mary Fieser Fellowship Award to continue her postodoctoral studies with Professor Cynthia Friend at Harvard University.  Professor Co’s research interest is in developing next generation battery materials including ultra-fast charge materials, high capacity materials, solid-state batteries, and flexible batteries.  She is also interested in electrocatalytic materials for fuel cells and the conversion of CO2 to value-added chemicals.  Additionally, her group has developed analytical tools to probe electrode and chemical processes in real-time measurement to understand mechanistic pathways of electrochemical reactions for applications related to energy conversion and storage.  Professor Co received an NSF-CAREER award in 2014.  She currently serves as an Associate Editor for ACS Applied Energy Materials.  She is also on the editorial advisory board of the Journal of Applied Electrochemistry, the Board of Directors of the Society for Electroanalytical Chemistry, and a member of the Physical and Analytical Electrochemistry Division of the ECS.
