Ultrasensitive resistivity-based ethanol sensor based on the use of CeO-FeO core-shell microclusters.

This paper presents a method for synthesis of CeO-FeO core-shell nanoparticles (CSNPs). These are shown to display enhanced ethanol sensing properties. Synthesis was done via a two-step process, starting with co-precipitation and followed by applying a sol-gel method.

NiO decorated CeO nanostructures as room temperature isopropanol gas sensors.

Heterostructures developed using CeO show promising peculiarities in the field of metal oxide gas sensors due to the great variations in the resistance during the adsorption and desorption processes. NiO decorated CeO nanostructures (NiO/CeO) were synthesized a facile two-step process. High resolution transmission electron microscopy (HRTEM) results revealed the perfect decoration of NiO on the CeO surface.
