Thermoelectricity Enhanced Electrocatalysis
Nano Letters, 2017We show that thermoelectric materials can function as electrocatalysts and use thermoelectric voltage generated to initiate and boost electrocatalytic reactions. The electrocatalytic activity is promoted by the use of nanostructured thermoelectric materials in a hydrogen evolution reaction (HER) by the thermoelectricity generated from induced ...

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.

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 (

Single-molecule nanoscale electrocatalysis
Physical Chemistry Chemical Physics, 2010Nanoscale catalysts are important for electrocatalysis, especially in energy conversion as in photoelectrochemical cells and fuel cells. Understanding their reactivity is essential for improving their performances and designing new ones, but challenging due to their inherent structural heterogeneity.

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.
