Abstract
Semiconductive nanometer-sized NdVO4 was synthesized by a solution combustion reaction of Nd(NO3)3•6H2O, V(NO3)3 and urea as a fuel. The process was a convenient, environment friendly, inexpensive and efficient preparation method for the NdVO4 nanomaterial. Effects of the 800 ◦ C calcining temperature on the phase constituents was characterized by TG-DTA, X-ray diffraction (XRD), which was used to confirm the material’s structure. The as-prepared samples were further characterized by scanning electron microscopy (SEM) equipped with energydispersive X-ray spectroscopy (EDX), and transmission electron microscopy (TEM), to depict the crystallite microstructure. Conductance responses of the nanocrystalline NdVO4 thick film were measured by exposing the film to reducing gases like acetone, ethanol, ammonia (NH3), and liquefied petroleum gas (LPG). It was found that the sensors exhibited various sensing responses to these gases at different operating temperatures. Furthermore, the sensor exhibited a fast response and a good recovery. The results demonstrated that NdVO4 can be used as a new type of gas-sensing material which has a high sensitivity and good selectivity to Liquefied petroleum gas (LPG).
