Abstract

Following a recent short communication J Electroanal Chem 769 2016 1–4 in which we demonstrated the feasibility and proofofconcept results of using interdigitated metal electrodes to achieve highresolution in situ electrochemical solution NMR for studying electrochemically driven reactions such as those involved in electrolysis and electrocatalysis we report herein a more detailed technical description of the technique and its application to studying methanol and ethanol electrooxidation on PtRu and PtNiCu electrocatalysts13C NMR data from ethanol oxidation with a PtNiCu catalyst a C NMR resonances as a function of time showing the growth of all product peaks b Comparison of the final spectra of ethanol oxidation reactions performed with PtNiCu black upper and PtRu blue lower catalysts Differences in the relative intensities of the product peaks can be identifiedThis material is based upon work supported by the US Department of Energy Office of Science Office of Basic Energy Sciences Catalysis Program under Award Number DEFG0207ER15895 EGS also thanks financial support from the Georgetown College and Graduate School We also appreciate the help of Jasper Nijdam at GNuLab at Georgetown University for assistance with plasma deposition
