| Empirical electrocatalyst research generally consists of the synthesis and experimental characterization of catalysts and the analysis of electrolysis products by conventional analytical techniques.In-situelectron paramagnetic resonance spectro-electrochemistry provides an evidence-based in-depth understanding of the formed intermediates and the reaction mechanism enabling the desired tuning of electrocatalysts. The use of this technique has been underexploited because of the opposite requirements they impose on the conventional setup. In this work, a versatile electrode with commercially available indium tin oxide on polyethylene terephthalate (PET) was constructed for the first time which can fit inside commonly used flat cells. It allows reproducible electrodeposition of catalytic material combined with sensitive radical detection, owing to its large surface area and minimal disruption to the resonator's Q-factor. Moreover, with a resistivity of 8-10 omega sq(-1), the surface potential of the thin semiconductor electrode within the resonator was well-controlled, allowing targeted radical production. |
