Screening Anti-Oxidant Activity at Oil Microdroplet Triple Phase Boundary Electrodes

SAE Technical Paper Series, 2009
<div class="htmlview paragraph">Highly non-polar/non-conducting media such as natural or synthetic oils cannot be analysed by conventional single phase solution voltammetry, but it is shown here that, when they are deposited onto suitable basal plane pyrolytic graphite electrode surfaces, the triple phase boundary reaction zone in liquid | liquid

Precise Construction of the Triple-Phase Boundary and Its Antiphosphate Poisoning Effect in the Confined Region

Inorganic Chemistry
As a critical component for the oxygen reduction reaction (ORR), platinum (Pt) catalysts exhibit promising catalytic performance in High-temperature-proton exchange membrane fuel cells (HT-PEMFCs). Despite their success, HT-PEMFCs primarily utilize phosphoric acid-doped polybenzimidazole (PA-PBI) as the proton exchange membrane, and the phosphoric acid

Understanding the Roles of Double- and Triple-Phase Boundaries in High-Temperature CO ₂ Electrolysis

Nano Letters
High-temperature solid oxide electrolysis cells are promising for CO2-to-CO conversion with high selectivity and energy efficiency. However, the correlation between the electrolysis performance and electrode interface structure remains poorly understood.

Protons crossing triple phase boundaries based on a metal catalyst, Pd or Ni, and barium zirconate

Physical Chemistry Chemical Physics, 2013
Density functional theory calculations are used to investigate the energetics of protons crossing triple phase boundaries based on a metal catalyst, Pd or Ni, and barium zirconate. Our calculations show that the proton transfer reaction at these interfaces is controlled by the terminal layer of the electrolyte in contact with the metallic and gas ...

Electrochemical Role of Li‐Ligands at the Triple‐Phase Boundary in Li‐O₂ Batteries

Small
AbstractThe increasing global energy demand drives interest in high‐energy‐density alternatives to lithium‐ion batteries, with Li‐O2 batteries emerging as promising candidates due to their exceptionally high theoretical energy density. However, the gap between the theoretical and practical energy densities remains significant, primarily due to the ...

Existence of a positive solution to a nonlinear system of PDEs in a domain with a triple-phase boundary

2013
We consider a system of nonlinear PDEs describing the reaction-diffusion dynamics near a triple-phase boundary in the catalyst layer of hydrogen fuel cells. The system involves bulk diffusion and surface reaction-diffusion processes and is an approximation of a model with a thin layer.
