A highly sensitive and stable [Ru(bpy)3]2+ ECL sensor has been fabricated based on the multilayer films of Nafion-stabilized magnetic nanoparticles (Nafion/Fe3O4) formed on a platinum electrode surface by means of an external magnet.

We present an innovative electrochemical probe for the monitoring of pH, redox potential and conductivity in near-field rocks of deep geological radioactive waste repositories. The probe is composed of a monocrystalline antimony electrode for pH sensing, four AgCl/Ag-based reference or Cl- selective electrodes, one Ag₂S/Ag-based reference or S2- selective electrode, as well as four platinum ele...

The interaction between ionomer (ion-conducting polymer) and catalyst particles in porous electrodes of electrochemical energy-conversion devices is a critical yet poorly understood phenomenon that controls device performance. This interaction stems from the electrode precursor inks, which also governs porous-electrode morphology during formation. In this letter, we probe the origin interaction...

The demand of green hydrogen, that is, the hydrogen produced from water electrolysis, is expected to increase dramatically in coming years. State-of-the-art proton exchange membrane electrolysis (PEMWE) uses high loadings platinum group metals, such as Pt electrode where produced. Alternative electrodes based on phosphides, sulfides, nitrides, and other low-cost alternatives are under investiga...
