A major challenge with water splitting technology is to develop highly active and stable electrocatalysts for the oxygen evolution reaction (OER). IrO2 – based electrocatalysts are one of the most active electrocatalysts for proton exchange membrane (PEM) electrolysers, due to their excellent activity for the OER in acidic conditions. However, IrO2...

Microliter volume pH determination is of great importance in the biomedical and industrial applications. The current available pH meter and measurement techniques are hard to reach the high demand of microliter volume pH determination in a repeatable, stable, and sensitivity manner. This work aims to fill the gap of microliter volume pH measurement...

A novel IrO2-Ta2O5 coated titanium anode with TaOx interlayer was prepared using a facile method of thermal decomposition. The interlayer and the composite anodes of Ti/TaOx/IrO2-Ta2O5 were characterized with surface analytical techniques of XPS, XRD, SEM and EDS. The electrochemical properties of the composite anodes with different coats of the in...
La préservation de l’environnement et les besoins énergétiques croissants nécessitent le développement rapide d’alternatives aux énergies fossiles. Dans ce contexte, le dihydrogène est considéré comme le vecteur énergétique du futur. L’électrolyse de l’eau est une des voies les plus prometteuses pour produire de « l’hydrogène vert ». Parmi les défi...
The growing demand for energy and rising climate concerns call for an urgent need to decarbonize the highly polluting energy sector by adopting hydrogen economy. Polymer electrolyte membrane water electrolyzers (PEMWEs) are a promising technology to produce green hydrogen by water electrolysis at high efficiencies and low temperatures. The hydrogen...
