This research provides a proof of concept for the fabrication of boron-doped diamond coated mesh electrodes and for their use as porous anodes in a zero-gap PEM electrolyzer for anodic production of H₂O₂ by selective oxidation of water. The anodic production of H₂O₂ is paired with cathodic hydrogen gas evolution. The study includes analyzing the effect of pulsed-current electrolysis, which is shown to increase the Faradaic efficiency of H₂O₂ formation. Compared to constant current electrolysis, pulsed operation with an optimal current on-to-off time ratio opens possibilities to significantly increase the Faradaic efficiency of H₂O₂ formation. This research, funded by the NWO and by the industrial partners VSPARTICLE and FUMATECH BWT GmbH, is an international collaboration lead by Marco Altomare, in collaboration with Adam Vass, Georgios Katsoukis and Guido Mul in the UT’s Department of Chemical Engineering, and with Michail Tsampas at DIFFER, Maximilian Göltz, Hanadi Ghanem, and Stefan Rosiwal at FAU Erlangen-Nürnberg, Tanja Franken at Technische Universität Darmstadt, and Regina Palkovits at Forschungszentrum Jülich, RWTH Aachen University and Max Planck Institute.
