H<sub>2</sub>O<sub>2</sub> Synthesis with Molecular Electrocatalysts Enables Substantial Current Densities in a Flow Cell Using Gas Diffusion Electrodes.
Ontology highlight
ABSTRACT: The development of catalysts for the two-electron oxygen reduction reaction (ORR) toward H2O2 generation has gained substantial interest, as well as studying their activity in advanced electrochemical cell configurations. However, molecular ORR catalysts are seldom studied outside of the idealized environment of a rotating disk electrode (RDE) setup. Consequently, the catalytic currents reported for all molecular catalysts are limited by the mass transport of oxygen, and their properties in industrially relevant reactor configurations have remained unexplored. To assess their full potential, we report herein the application of a molecular, copper-based ORR catalyst, Cu-(tmpa) (tmpa = tris-(2-pyridylmethyl)-amine), in a cell configuration with gas diffusion electrodes
