Assessing the Extent of Potential Inversion by Cyclic Voltammetry: Theory, Pitfalls, and Application to a Nickel Complex with Redox-Active Iminosemiquinone Ligands

Cheriehan Hessin et al.

Summary: Potential inversion refers to the phenomenon where the second electron transfer is easier than the first, and it is significant for understanding enzyme catalysis and developing efficient catalysts. Currently, there is a lack of analytical predictions to interpret voltammetric peak potentials when potential inversion occurs, and cyclic voltammograms are often analyzed without considering overfitting or estimating error. In this study, a theory for voltammetry of two-electron redox species in the irreversible limit is formulated and applied to analyze the voltammetry of a nickel complex with redox-active ligands, highlighting the intrinsic underdetermination of the model. Characterizing the thermodynamics of two-electron electron-transfer reactions is crucial for catalyst design.

Electrochemical Kinetics Support a Second Coordination Sphere Mechanism in Metal-Based Formate Dehydrogenase

Marta Meneghello et al.

Summary: Metal-based formate dehydrogenases are enzymes that require molybdenum or tungsten ions to catalyze the conversion between formate and CO2. The coordination of the metal ion in the active form prevents direct binding of formate to the metal. The study's findings provide strong evidence for the hypothesis that the oxidation of formate occurs in the second coordination sphere of the metal.

Applicability of conventional protocols for benchmarking of unidirectional and bidirectional multi-electron homogeneous molecular catalysts beyond the pure kinetic regime

A. Molina et al.

Summary: Accurate and rational benchmarking of molecular catalysts is crucial for achieving high selectivity and efficiency in electrochemical reactions. However, the analysis of complex multi-electron, multi-step processes in homogeneous catalytic schemes is mainly based on methods developed for the simple one-electron catalytic mechanism. This study investigates the applicability of these protocols for multi-electron catalysts and proposes novel tools to overcome inaccuracies caused by the widely-used pure kinetic conditions.

Reversible or Irreversible Catalysis of H+/H2 Conversion by FeFe Hydrogenases

Andrea Fasano et al.

Summary: This study investigates the thermodynamic driving force required for fast catalysis in bidirectional molecular catalysts and the mechanism of irreversible catalysis reactions. The research found that the catalytic irreversibility of a specific enzyme can be explained without invoking slow interfacial electron transfer or variations in the mechanism, with the same catalytic pathway being used in both directions of the reaction.

Catalytic bias in oxidation-reduction catalysis

David W. Mulder et al.

Summary: Catalytic bias refers to the propensity of a reaction catalyst to accelerate the rate of reaction differently in one direction versus the other under non-equilibrium conditions. Enzyme's inherent bias in biocatalysis is advantageous for promoting efficiency and coordination, while directional catalytic bias is sought after in industrial chemical catalysis.
