Abstract

: In display work we choose Sol-gel route for synthesis of LaCrO3 nanomaterial which found to act as a H2S gas sensor. Characterization of it was done by XRD, SEM, TEM, EDX etc. From XRD we got a nanomaterial having average crystallite size 13.01nm having JCPDS Card No. 33-0701 from which LaCrO3is having a perovskite type orthorhombic material. The SEM spectrum shows particles which dispersed on surface and the EDX indiates the elemental composition. By TEM we confirmed its particle size is 39.48nm. The bands596 cm- for La –O stretch and 416.04 cm- for Cr-O stretch showed by FTIR studies. From this material thick film were prepared by simple screen printing technique. Then the films were calcinated and were exposed to various gases at different temperature. The LaCrO3 sensor shows selectivity for H2S gas at working temperature range from 1500C to 2500C. Its response and recovery time were also studied.
