The oxidation of palladium nanoparticles causes the performance degradation of alkaline direct ethanol fuel cells. Quantifying this oxidation is a task of tremendous importance to design mitigation strategies that extend the service life of catalysts and devices. Here, we show that the Fixed Energy X-ray Absorption Voltammetry (FEXRAV) can provide ...

The influence of the carbon support characteristics on Pd loading, dispersion and activity in Pd/C catalysts has been analyzed. Several carbon nanomaterials, including multi-walled CNTs, nitrogen-doped CNTs, sulfur-doped CNTs, large- and small-diameter nanofibers, few-layer graphene, and a fibrous carbon have been produced, functionalized, defuncti...

A pH sensor was fabricated using a modified hydrogen-storage palladium electrode. The Pd electrode stores H₂ generated electrochemically at suitable potentials. After the Pd electrode had become coated with palladium hydride (PdHₓ), the resting potential of the modified Pd electrode responded to changes in the pH with a near-Nernstian response of −...
