We have recently introduced corrole metal complexes (metallocorroles) as catalysts for various energy-relevant reactions. This includes those that are of prime importance for the electrochemical splitting of water into its elements, the hydrogen and oxygen evolution reactions. Tuning of the redox potentials, M(I)/M(II) for HER and M(III)/M(IV) for OER (M= Fe, Co, or Mn), is achieved via variations of substituents on the corrole ligand. These hypothesis-driven changes allow for the highly desired shifting of electrocatalytic onset potentials.

On top of the already published results listed below, new approaches and novel catalysts will be disclosed.
