A Homogeneously Catalyzed Paired Electrolytic Cell for Hydrogen Peroxide Production
Angewandte Chemie, Volume 138, Issue 19, 4 May 2026.Cu(tmpa) and Sn‐TMPyP are compatible and efficient catalysts for 2e−‐ORR and 2e−‐WOR, respectively, which have been employed to assemble an efficient paired electrochemical cell for H2O2 production. The presence of a carbonate buffer is essential to achieve a high activity in the anode compartment, while control over mass transport is essential for a ...

Altering the Coordination of Iron Porphyrins by Ionic Liquid Nanodomains in Mixed Solvent Systems [PDF]
, 2017 The solvent environment around iron porphyrin complexes was examined using mixed molecular/RTIL (room temperature ionic liquid) solutions. The formation of nanodomains in these solutions provides different solvation environments for substrates that could
