Abstract

Crystalline CeO2/TiO2 CORE/SHELL nanoparticles with and without hydroxypropyl cellulose were synthesized via a three-step process. The CeO2/TiO2 CORE/SHELL structure formation was confirmed by x-ray diffraction (XRD), energy dispersive spectroscopy (EDS) and field emission scanning electron microscopy (FESEM). The nanoparticles exhibited notable sensitivity to volatile organic compounds at room temperature and selective gas sensing properties. CeO2/TiO2 core/ shell nanoparticles were showed at 340 ppm of ethanol with and without HPC sensitivity 16 and 10 units, respectively. Short response and recovery times and low temperature sensing were measured as other improvement properties of the sensors. The sensing mechanism nanoparticles were explained based on the change of the heterojunction barrier formed at the interface of CeO2 and TiO2.
