  abstract = {A comparative study on the sensing properties of nanoparticles ZnO+ x wt% CeO2 and SnO2+ x wt% CeO2 (x = 0, 2, 4 and 6) sensors sintered at 400 oC toward ethanol gas have been carried out. The crystal structure and the particle size of the prepared samples were investigated by using XRD, IR and TEM techniques. XRD and IR investigation confirmed that the prepared ZnO and SnO2 have good crystalline character with average crystallite size of 34.5 and 7.2 nm respectively. The TEM study showed that the particles of the pure ZnO sensor nearly show a hexagonal shape which enhanced by the addition of CeO2. While the particles of the SnO2 sensors displayed fine structures with spherical shape. The electrical conductivity behavior of both oxides samples was nearly similar and the electrical conductivity values of ZnO sensors are higher than that of SnO2 sensors at the same conditions. The obtained gas sensing results showed that the SnO2 based sensors have high sensitivity values toward ethanol gas with lower operating temperature than that of ZnO based sensors. On the other hand, ZnO based sensors have slightly rapid response time and short recovery time than that of SnO2 based sensors.},
