Modelling a cyclic staircase voltammetry of two electron transfers coupled by a chemical reaction on a rotating disk electrode [PDF]

Journal of the Serbian Chemical Society
Two electrode reactions that are coupled by a chemical reaction are called an ECE mechanism. The model of this mechanism which has an unstable intermediate is developed for staircase voltammetry on the rotating disk electrode.

High Sensitivity of Electron Transfer Rates within Nafion Coatings Saturated with Os(bpy)^(2+)_3 to the Extent of Hydration of the Coating [PDF]

, 1995
The sensitivity of the electrochemical responses obtained from electroactive counterions incorporated in Nafion coatings to the extent of hydration of the coatings^(27-38) is shown to be enhanced significantly when the electroactive ion is the only ...

Using a dual plasma process to produce cobalt--polypyrrole catalysts for the oxygen reduction reaction in fuel cells -- part I: characterisation of the catalytic activity and surface structure

, 2012
A new dual plasma coating process to produce platinum-free catalysts for the oxygen reduction reaction in a fuel cell is introduced. The catalysts thus produced were analysed with various methods.

Antimony-doped graphene nanoplatelets [PDF]

, 2015
Heteroatom doping into the graphitic frameworks have been intensively studied for the development of metal-free electrocatalysts. However, the choice of heteroatoms is limited to non-metallic elements and heteroatom-doped graphitic materials do not ...

Elucidating the Role of Surface Ligands on the Oxidative Etching of Au Bipyramids During Photothermia Using Liquid Cell Transmission Electron Microscopy

Advanced Functional Materials, EarlyView.
Gold bipyramids can act as efficient plasmonic nanoheaters, but they often reshape during laser heating. This study shows that oxygen nanobubbles drive oxidative etching and that surface ligands control stability. CTAB‐ and citrate‐coated particles blunt and lose optical performance, whereas polystyrene sulfonate preserves shape and heating by ...

Balancing Electrons to Break the Activity‐Selectivity Trade‐Off in H2O2 Electrosynthesis

Advanced Functional Materials, EarlyView.
Carrier‐concentration balancing in CuS is achieved by coupling cobalt dopants with cobalt vacancies, converting CuS from p‐ to n‐type to accelerate 2e− ORR while withdrawing excess carriers to optimize *OOH binding for H2O2 desorption. The catalyst reaches 8.14 mol g−1 h−1 with >84% selectivity in 1.0 M KOH and drives robust electro‐Fenton dye ...

Role of the reversible electrochemical deprotonation of phosphate species in anaerobic biocorrosion of steels [PDF]

, 2007
Sulphate reducing bacteria are known to play a major role in anaerobic microbiological influenced corrosion of steels, but mechanisms behind their influence are still source of debates as certain phenomena remain unexplained.

Carbon Shell‐Encapsulated PtFe Catalysts in High Temperature Polymer Electrolyte Membrane Fuel Cells: Balancing Molecular Sieving and Diffusion for Enhanced Reactant Access

Advanced Functional Materials, EarlyView.
Scanning electrochemical microscopy reveals reactant diffusion through porous carbon shells to PtFe cores, while the carbon‐encapsulated PtFe enables high‐performance HT‐PEMFC operation by sieving phosphate ions that induce catalyst poisoning. ABSTRACT High‐temperature polymer electrolyte membrane fuel cells (HT‐PEMFCs) operating at 160°C on phosphoric
