Abstract: Semiconductive nanoparticles of LaAlO3 were synthesized by a solution combustion technique. This process is a convenient, environment friendly, inexpensive and efficient for the preparation of LaAlO3 nanomaterial. The synthesized material is characterized by Thermo gravimetric Differential analysis (TG/DTA), X-ray Diffraction studied (XRD), Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) techniques. Conductance response of the nanocrystalline LaAlO3 pellet is measured by exposing the pellet to reducing gases like ammonia, ethanol, acetone. The sensor exhibited a fast response and a good recovery. The results demonstrated that LaAlO3 can be used as a gas-sensing material which has a high sensitivity and good selectivity 80% to ammonia gas at 50 ppm.

 

Keywords: LaAlO3, ammonia gas sensor, XRD, TEM, gas response
