Single Entity Electrocatalysis
Chemical ReviewsMaking a measurement over millions of nanoparticles or exposed crystal facets seldom reports on reactivity of a single nanoparticle or facet, which may depart drastically from ensemble measurements. Within the past 30 years, science has moved toward studying the reactivity of single atoms, molecules, and nanoparticles, one at a time.

Adsorption Energy in Oxygen Electrocatalysis
Chemical Reviews, 2022Adsorption energy (AE) of reactive intermediate is currently the most important descriptor for electrochemical reactions (e.g., water electrolysis, hydrogen fuel cell, electrochemical nitrogen fixation, electrochemical carbon dioxide reduction, etc.), which can bridge the gap between catalyst's structure and activity.

AbstractA selection of recent theoretical and experimental studies on electrolytic hydrogen evolution is presented. It is demonstrated with well‐defined model surfaces that this reaction is a very structure‐sensitive process. Crystallographic orientation, defect density and surface composition are parameters that determine the local geometric and ...

Nanoarchitectonics of Metallene Materials for Electrocatalysis
ACS Nano, 2023Controlling the synthesis of metal nanostructures is one approach for catalyst engineering and performance optimization in electrocatalysis. As an emerging class of unconventional electrocatalysts, two-dimensional (2D) metallene electrocatalysts with ultrathin sheet-like morphology have gained ever-growing attention and exhibited superior performance ...

AbstractRenewable electricity‐powered electrocatalysis technologies occupy a central position in clean energy conversion and the pursuit of a net‐zero carbon emission future. Water can serve multiple roles in electrocatalytic reactions, for instance, as a reaction medium, reactant, modifier, promoter, etc.

Insights into electrocatalysis
Phys. Chem. Chem. Phys., 2012When standard reversible potentials for bulk solution reactions, U(0), are known, the reversible potentials when the reactant and product are adsorbed on an electrocatalyst surface, U(surf)(rev), are given in terms of these potentials and the adsorption Gibbs energy bond strengths: U(surf)(rev) = U0 + D(ads)G (Ox)/F-Δ(ads)G (R)/F (i). When the Δ(ads)G (

The Vanadium Redox Reactions – Electrocatalysis versus Non‐Electrocatalysis
ChemPhysChem, 2019AbstractCatalytic effects of surface groups on porous carbon electrodes are claimed in literature for the redox reactions V(II)/V(III) and V(IV)/V(V). The literature is critically analysed also in relation to work of this group. A method how to overcome the problem of assessing the electrochemically active surface area on porous electrodes is presented.
