Journal ArticleDOI
Molecular electrocatalysts for the oxygen reduction reaction
TL;DR: In this paper, a review of recent developments in homogeneous and heterogeneous molecular ORR catalysis, placing emphasis on reaction mechanisms and the factors governing rates and selectivities, is presented.
Journal ArticleDOI
Cobalt Corrole Catalyst for Efficient Hydrogen Evolution Reaction from H2O under Ambient Conditions: Reactivity, Spectroscopy, and Density Functional Theory Calculations
Biswajit Mondal,Kushal Sengupta,Atanu Rana,Atif Mahammed,Mark Botoshansky,Somdatta Ghosh Dey,Zeev Gross,Abhishek Dey +7 more
TL;DR: Density functional theory (DFT) calculations indicate that the electron density on a putative hydride species is delocalized off from the H atom into the macrocycle, which makes the protonation of a [Co(III)-H](-) species the rate determining step for the HER consistent with the experimental data.
Journal ArticleDOI
The cobalt corrole catalyzed hydrogen evolution reaction: surprising electronic effects and characterization of key reaction intermediates
TL;DR: A surprising effect of halide substituents on reduction potentials and catalytic activity of halogenated cobalt corroles has been deduced by experimental and computational methods as discussed by the authors.
Journal ArticleDOI
Intermediates Involved in the 2e–/2H+ Reduction of CO2 to CO by Iron(0) Porphyrin
TL;DR: The reduction of CO2 by an iron porphyrin complex with a hydrogen bonding distal pocket involves at least two intermediates and the facile heterolytic cleavage of the C-OH bond in intermediate II requires strong acids.
Journal ArticleDOI
Rational Design of Mononuclear Iron Porphyrins for Facile and Selective 4e–/4H+ O2 Reduction: Activation of O–O Bond by 2nd Sphere Hydrogen Bonding
Sarmistha Bhunia,Atanu Rana,Pronay Roy,Daniel J. Martin,Michael L. Pegis,Michael L. Pegis,Bijan Roy,Abhishek Dey +7 more
TL;DR: A series of mononuclear iron porphyrin complexes are rationally designed to achieve efficient O-O bond activation and site-selective proton transfer to effect facile and selective electrochemical reduction of O2 to water with rate constants higher than all known heme/Cu complexes.
