Cobalt(IV) corroles as catalysts for the electroreduction of O2: Reactions of heterobimetallic dyads containing a face-to-face linked Fe(III) or Mn(III) porphyrin

Zeolite-encapsulated M(Co,Fe,Mn)(SALEN) complexes modified glassy carbon electrodes and their application in oxygen reduction

“…Fuerte et al [53] and his group reported that CoTPP and FeTPP complexes supported onto MCM-41 and ITQ-6 were good electrocatalysts for ORR by two-electron process. According to Kadish et al [64], two key points are important for estimating the quality of a catalyst for O 2 reduction. One point, also the more obvious, is the number of electrons, which should be close to 4.0 for producing H 2 O rather than close to 2.0 for forming H 2 O 2 , and another point is the potential of O 2 catalytic reduction.…”

CO electro-oxidation by carbon-supported Rh tetraphenylporphyrins that have o-methyl groups on meso-phenyl substituents

“…This effect also weakens the p-p interaction between the porphyrin ring and the carbon black. Bulky substituents on macrocycles decrease the interaction with an electrode [30,31]. This weak interaction would be unfavorable for the electron transfer from the Rh atom to the carbon black.…”

Electrochemistry of Fe(IV) and Mn(IV) corroles containing meso-dichlorophenyl substituents and the use of these compounds as catalysts for the electroreduction of dioxygen in acid media

“…We have earlier examined numerous cobalt triarylcorroles 16,17,19,24,25 phenyl rings of a triarylcorrole will significantly affect the catalytic activity of these compounds towards the reduction of O 2 .…”
