Original Kurzfassung:
In this talk, we demonstrate a method to tune OER/ORR selectivity by adjusting the local metal density through simple oligo-/polymerization of novel ?-conjugated metal A2B and A3-corroles to linear and two-dimensional matrix structures. [1] These heterogeneous catalysts exhibit remarkable physicochemical properties, fast charge transfer kinetics, electrochemical reversibility, and high durability. As an example, unselective three-electron transfer kinetics with n = 2.5?2.9 in between -0.20 V and +0.40 V vs. RHE are detected with the ?-conjugated cobalt(III) A2B- corrole polymers. Highly selective four-electron kinetics with n = 3.7 in between -0.20 V and +0.40 V vs. RHE are detected by employing the cobalt A3-corrole oligomers during the ORR catalysis.
