Abstract Pr0.1Ce0.9O2 (PCO) films, with columnar structure containing voids, were fabricated by pulsed laser deposition (PLD) and integrated into YSZ-based potentiometric gas sensor as a sensing electrodes (SEs). Sensors with PCO film thicknesses of 550, 1100 and 2200 nm, fabricated by controlling the number of PLD shots of 750, 1500 and 3000 respectively, were examined over the temperature range of 450‒600 °C. The sensor output voltage, E, of all sensors showed increasing negative change with i...

In interfacial charge-transfer reactions, the complexity of the reaction pathway increases with the number of charges transferred, and becomes even greater when the reaction involves both electrons (charge) and ions (mass). These so-called mixed ion and electron transfer (MIET) reactions are crucial in intercalation/insertion electrochemistry, such as that occurring in oxygen reduction/evolution electrocatalysts and lithium-ion battery electrodes. Understanding MIET reaction pathways, particular...

Abstract This work reports on the gas sensor response of undecorated 1D stannous oxide nanobelts and those decorated with Pt and Pd nanoparticles. The sensor device responses to H2, CO and NO2 were measured in dry air baseline atmosphere as functions of the analyte concentration (1–1000 ppm) and temperature (100-350 °C). Noble metal decorated SnO devices exhibited enhanced chemical sensitization, resulting in increased sensitivity upon exposure to reducing gases at different working temperatures...

Abstract Cathodic electrochemical deposition, a simple and cost-effective route for fabricating ceria nanostructures, has attracted much attention in catalysis and renewable energy technologies. However, electrochemical nucleation and growth mechanisms that determine the nanoscale architecture of ceria films during deposition have not yet been clarified. In this study, we analyze current and mass-time transients and thin film microstructures as functions of applied potential and temperature. We ...
