(Keynote) Interpretation of Oxygen Reduction Activity Volcano Correlations for MN4 Molecular Catalysts Compared to Those for Metallic Electrodes

Autor: Jose H Zagal, Federico Tasca, Ingrid Ponce

Publikováno v: ECS Meeting Abstracts. :2057-2057

A classical well-known reactivity index in electrocatalysis is the binding energy of key intermediates to the active sites. For example, this is well documented for the catalytic activity of metal electrodes for the oxygen reduction reaction (ORR)[1]

(Invited) Tuning the Electrocatalytic Activity of Fe Phthalocyanine Via Axial Ligation to Multiwalled Carbon Nanotubes and Via Ligand Substitution: Electrochemistry of l-Cysteine and l-Cystine

Autor: Jose H Zagal

Publikováno v: ECS Meeting Abstracts. :764-764

Multiwalled carbon nanotubes (MWCNTs) are excellent platforms for the fabrication of active electrodes for electrocatalysis and electrochemical sensors [1], especially by chemical modification with molecules of known activity. We have studied the ele

(Invited) Oxygen Reduction Reaction at MN4 and MN5 Catalysts - Calculated and Experimental O2-Fe Binding Energies, Activity Indexes, Volcano Correlations

Autor: Federico Tasca, Jose H Zagal, Walter Orellana, Jose Marco

Publikováno v: ECS Meeting Abstracts. :763-763

The oxygen reduction reaction (ORR) is a fundamental chemical reaction in industrial processes as well as in living systems, being O2, the final electron (e-) acceptor of many reactions. Since then its importance in the fuel cell technology where ene

(Invited) Climbing over the Volcano Correlation for O2 Reduction By the Effect of a Pyridine Axial Ligand Bound to Co Phthalocyanine Compared to Vitamin B12. 4 Versus 2 Electron Reduction of O2

Autor: Jose H Zagal, Federico Tasca, Karinna Neira, Jorge Riquelme, Patricio Hermosilla, Diego Venegas, Walter Orellana

Publikováno v: ECS Meeting Abstracts. :2187-2187

CoN4 macrocyclic complexes like Co phthalocyanines (CoPc) have been extensively studied as electrocatalysts for the ORR since the discovery by Jasinski [1] but they only promote the 2-e reduction of O2 to give peroxide, this, delivering less energy w
