Operando x-ray spectroscopy investigation of hydrogen reaction mechanism on novel core-shell electrocatalysts

In this project, we use x-ray absorption spectroscopy study on operando electrocatalysis in alkaline media with a novel core-shell nanoparticulate system Pd@CeOx as catalyst, supported on single-walled carbon nanotubes (SWNT). The catalyst material has been developed in-house, and shows highly promising activity for hydrogen evolution and oxidation reactions. XANES and EXAFS results of the Ce and Pd will enable further rational design of the catalyst.
