Investigation of NiFe(Ox) nanoparticles for water splitting, and Introduction to NRC Mississauga

Water electrolysis can provide a means to produce hydrogen using renewable electricity. The storage of energy using hydrogen as fuel is hindered by the sluggish kinetic of the oxygen evolution reaction. In order for these devices to be developed on a large scale, more active catalysts are needed. NiFe oxy-hydroxides are the current state-of-the-art catalysts for oxygen evolution. The origin of their activity is currently under intense debate. For example, there is uncertainty whether the bulk or the surface is active. In order to improve the catalysis of this reaction, it is important to gain further understanding of the factors controlling the intrinsic activity. Dr. Claudie Roy will share insights about the intrinsic activity of these catalysts drawn from systematic evaluations of well characterized model systems of NiFe nanoparticles of varying size.


Dr. Claudie Roy is a Research Officer at the National Research Council of Canada (NRC), where she leads the CO2 conversion thrust of the Materials for Clean Fuels Challenge Program. Moreover, as an inaugural scientist at the NRC’s new advanced materials research facility under construction in Mississauga, Dr. Roy plays a central role in the start-up of the laboratories and research operations, in particular for the facility’s Materials for Electrocatalysis and Smart Materials for Smart Objects focal areas. Prior to joining the NRC, Dr. Roy graduated with a Ph.D in Physics in from the Technical University of Denmark (DTU) under the supervision of Professor Ib Chorkendorff and Senior Lecturer Ifan Stephens. She specialized in the development of catalysts for application in energy storage and conversion technologies. More specifically, she worked on various projects including the development of materials for renewable energy storage (electrolysers) and fuel cell applications, and on the investigation of CO2 reduction processes.
