Abstract : In this contribution, nanoparticles composed of ZnO-CeO 2 were synthesized by simple and efficient low temperature process and employed for the development of effective chemical sensor as well as photo-catalyst for the removal of environmental contaminants. Field emission scanning electron microscopy (FESEM), X-ray powder diffraction (XRD), Raman spectroscopy and Fourier transform infrared spectroscopy (FTIR) were used to confirmed the morphology and structure of the synthesized ZnO-CeO 2 nanomaterial which revealed well crystalline aggregated nanoparticles with average diameters of ∼50±10nm. The composition of the nanoparticles was obtained by using EDS spectroscopy while the optical property was measured using UV-vis absorption spectrum. Photocatalytic degradation of acridine orange (AO) and methylene blue (MB) dyes has been carried out using ZnO-CeO 2 nanoparticles, which showed 92.1% degradation for AO and 80.7% degradation for MB in 170min of irradiation time. The analytical performance of ZnO-CeO 2 nanoparticles fabricated ethanol sensor exhibited higher sensitivity (2.1949μAcm -2mM -1) as well as lower detection limit (0.6±0.05mM) in short response time.
