Journal ArticleDOI
Metallophthalocyanines as catalysts in electrochemical reactions
TL;DR: The factor that controls the activity of these chelates is not fully understood but parameters such as redox potentials of the metal and electronic structure appear to be crucial as discussed by the authors.
Journal ArticleDOI
Metallophthalocyanine-based molecular materials as catalysts for electrochemical reactions
TL;DR: In this article, the authors show that the formal potential of a metallophthalocyanine complex needs to be in a rather narrow potential window for achieving maximum activity, probably corresponding to surface coverages of an M-molecule adduct equal to 0.5.
Journal ArticleDOI
Reactivity Descriptors for the Activity of Molecular MN4 Catalysts for the Oxygen Reduction Reaction.
José H. Zagal,Marc T. M. Koper +1 more
TL;DR: There is a correlation between the MIII /MII redox potential of MN4 chelates and the M-O2 binding energies, and the suggested descriptors also apply to heat-treated pyrolyzed MN4 catalysts.
BookDOI
N4-Macrocyclic Metal Complexes
TL;DR: Theoretical insights on the Chemical Reactivity of Metalloporphyrins using Density Functional Theory were provided in this paper, where a billion-year-old Oxygen Cathode that actually works: Respiratory Oxygen Reduction and its Biomimetic Analogs.
Journal ArticleDOI
Electrocatalytic activity of metal phthalocyanines for oxygen reduction
TL;DR: In this paper, a comparative study of the electrocatalytic activity of metallophthalocyanines for O2 reduction in alkaline and acid media was conducted using H2Pc, VOTsPc and CrTsPc.
