PCS members Shreyas Harsha, Lasse Wichmann, Guido Mul, and Marco Altomare recently had an article published in ChemElectroChem 2025 on 'An Adapted Rotating Disk Electrode Setup to Test Nonstandard-Disk Electrodes: On the Enhanced Hydrogen Evolution Performance of Model Dewetted Pt Nanoparticles Versus Pt Thin Films under Hydrodynamic Conditions.'
A rotating-disk-electrode adapter is designed to investigate non-standard-disk-electrodes under defined mass transport conditions. The hydrogen evolution performance of model Pt films versus thermally dewetted Pt nanoparticle (NP) electrodes is tested. Dewetted NPs are significantly more active than films under both static and hydrodynamic conditions. Their higher activity is of a kinetic nature and is proposed to arise from metal–support interactions.
