Authors(3) :-A. V. Borhade, S. L. Sangle, D. R. Tope

The present study reports ecofriendly mechanochemical synthesis of PbMnO3, PbMnO3:SiO2 and PbMnO3:Al2O3 composite metal oxides for the first time. The polycrystalline product obtained was analyzed by various physical investigative techniques including FTIR, XRD, SEM, TEM and BET surface area. Screen printed thick films of PbMnO3 and modified PbMnO3 oxides were prepared to check the potential application for gas sensing properties for most toxic, combustible and hazardous gases CO, CO2, H2, Cl2, NH3 and H2S at different operating temperatures ranging from 500C to 400 0C. Among the synthesized sensor PbMnO3:SiO2 shows highest sensitivity (1740) towards NH3 at 50 0C as compared toPbMnO3 (71.42) to NH3 at 200 0C andPbMnO3:Al2O3 (315.8) toH2S at 2500C.This study signifies that sensor was observed to be highly sensitive and selective to NH3 and H2S gas.
