Study On Ammonia Gas Sensing Properties Of Indium Zinc Nanocomposites By Green Synthesis Method Using Mangifera Indica And Neem Gum

Abstract

This present paper outlines the synthesis of Indium Zinc nanocomposites using mangifera indica (IZO-1) and Neem gum (IZO-2)
by Green Synthesis method. The structural properties was analyzed by X-Ray diffraction technique (XRD), as well Thermo
gravimetric and differential thermal analysis (TG-DTA) was made for detecting their crystallization behavior. The results displayed
polycrystalline hexagonal wurtzite phase with (002) as strong prefentially growth and more pronounced peak at (100) as well as
(101) orientation. The smaller sized grains shows spherical morphology with polycrystalline in nature with SEM analysis. The
optical performance indicated optical energy band gap as 3.1 and 3.18ev.The FTIR analysis shows the functional groups existent
in synthesized In-ZnO NCs which displayed an intense band with sharp peaks at 3446.91, 3421.83cm-1 due to O-H stretching of
hydroxyl functional group respectively for IZO-1 and IZO-2.From the analysis results shows enhanced ammonia sensing
performance by simple synthesis, low-cost which gives excellent performance.
