Impactful Role of Cocatalysts on Molecular Electrocatalytic Hydrogen Production

Charles G. Margarit et al.

Summary: Hydrogen evolution from acetic acid is greatly accelerated by iron tetraphenylporphyrin in the presence of tertiary amine as a cocatalyst, with enhanced proton activity and a trans effect leading to higher efficiency. This study highlights the design principle of using a cocatalyst to enhance hydrogen evolution electrocatalysis in molecular systems.

Proton Relay in Iron Porphyrins for Hydrogen Evolution Reaction

Sarmistha Bhunia et al.

Summary: The presence of proton-transfer groups near the catalyst can enhance the efficiency of the hydrogen evolution reaction (HER). Investigations show that a simple iron porphyrin can catalyze the HER at FeI state without being reduced to its formal Fe-0 state, and the rate of HER becomes almost independent of the pK(a) of the external acid used in the presence of protonated distal residues.

Oriented Electrostatic Effects on O2 and CO2 Reduction by a Polycationic Iron Porphyrin

Daniel J. Martin et al.

Summary: The study demonstrates that a metalloporphyrin catalyst with four cationic groups can stabilize charged intermediates and catalyze ORR and CO2RR reactions with fast rates and low overpotentials. Each of the four atropisomers of the metalloporphyrin show differences in maximum turnover frequencies and overpotentials for the two reactions, highlighting the complexity of charge positioning in affecting the thermodynamics and kinetics of multistep molecular electrochemical transformations.

Linear Free Energy Relationships in Hydrogen Evolution Catalysis by a Cobalt Tripeptide in Water

Jose L. Alvarez-Hernandez et al.

Summary: The study found that in buffered water, the cobalt tripeptide's catalytic rate constants for hydrogen production were significantly higher than when water was the only proton source, indicating that buffer acid can outcompete water as a proton donor. Additionally, the rate of hydrogen evolution catalyzed by the cobalt tripeptide was found to be dependent on the buffer-acid pK(a) and independent of pH.
