The Preparation and Electrochemical Properties of Perovskite La0.6Sr0.4CoO3-d for Catalytic Reduction of Oxygen

International Journal of Electrochemical Science, 2017
La0.6Sr0.4CoO3-d powder in nanoscale was produced through flame spray synthesis (FSS), which was a process method of particles in large scale. Then, the catalytic performance of the powder as a bi- functional catalyst towards oxygen evolution reaction ...

Three-electrode current-voltage measurements on erbia-stabilized bismuth oxide with sputtered noble metal electrodes [PDF]

, 1992
The anodic and cathodic polarization behaviour of sputtered porous gold electrodes on (Bi2O3)0.75(Er2O3)0.25 (abbreviated BE25) was studied as function of temperature and oxygen partial pressure using a three-electrode cell.

Nitrogen loss and oxygen evolution reaction activity of perovskite oxynitrides

, 2019
Perovskite oxynitride photocatalysts were reported by experiment to evolve small amounts of N$_2$ due to the self-oxidation of nitrogen ions by photo-generated holes. The N$_2$ evolution rate was observed to decrease with increasing reaction time and was

Hybrid Co3O4@Co9S8 Electrocatalysts for Oxygen Evolution Reaction

Frontiers in Materials, 2019
It is very essential to design an efficient and low-cost electrocatalyst for oxygen evolution reaction (OER). In this work, we report synthesis of Co3O4@Co9S8 heterostructures (Co-HSs) by employing Co3O4 nanowires (Co-NWs) as the precursor on nickel foam
