Hydrophobicity of CO2 gas diffusion electrodes
Joule, 2021In Nature Communications, Hu, Feng, and their colleagues present a scalable, facile method to tune the hydrophobicity of CO2 reduction gas diffusion electrodes by adding polytetrafluoroethylene (PTFE) nanopowder into the catalyst ink. For a copper catalyst CO2 reduction electrode, the additive significantly enhances CO2 reduction performance and ...

Amperometric gas‐diffusion/enzyme electrode
Electroanalysis, 1995AbstractAn amperometric enzyme gas‐diffusion electrode has been developed which combines a porous, air breathing gas‐diffusion electrode with an enzyme [glucose oxidase (GOD)] immobilized with Nation into its porous catalytic layer. The catalytic layer contains pyrolyzed Co‐ tetramethoxyphenylporphyrine (CoTMPP), which is very active towards the ...

Microfabricated gas-diffusion electrodes
Journal of Electroanalytical Chemistry, 1992Abstract Gas-diffusion electrodes with uniform openings were prepared by electrodeposition of silver on microfabricated metal mesh. The porous metallic structures were non-wetting and allowed operating pressures up to 2 atm (0.2 MPa). From the polarization data for oxygen reduction on these electrodes, the decrease in contact angle with pressure ...

Gas diffusion and electrolyte penetration in porous gas diffusion electrodes
Electrochimica Acta, 1977Abstract Gas diffusion and electrolyte penetration in wetproofed gas diffusion electrodes were studied using layers of PTFE-bonded carbon. Minor variations in fabrication and testing procedures resulted in very large variations in catalyst layer wetting characteristics and permeability for gases.

Enzyme/gas-diffusion electrodes for determination of phenol
Sensors and Actuators B: Chemical, 1996Abstract An enzyme/gas diffusion electrode for the determination of phenol concentration is investigated comprising a new type of porous hydrophobic carbon electrode (made from acetylene black treated with PTFE by a special technology) on which enzyme tyrosinase is immobilized. In the enzyme/gas-diffusion electrode the oxygen needed for the enzymatic
