A Study on Synthesis and Assessment of Thermal Stability of MnO2-Ag Nano Composites

Abstract

Manganese dioxide (MnO₂) is a versatile material with remarkable physicochemical properties, making it as an essential material. Silver Nanoparticles (Ag-NPs) have significance for their unique property, thermal Stability. In the present research, MnO₂-Ag nanocomposites were synthesized by the hydrothermal method in three different ratios, viz., 1:2(B-1), 1:1(B-2), and 2:1(B-3), respectively. The synthesized nanocomposites were characterized by Thermogravimetric Analysis(TGA) and confirmed by its thermogram that the composite 1:1(B-2) has higher thermal stability(20-600°C range) compared to the thermal stabilities of the remaining composites 1:2(B-1) and 2:1(B-3) respectively. The nanocomposites MnO₂-Ag (B-1) with 1:2 ratio exhibited lower thermal stability and may be considered for use as a suitable component in electric storage batteries like Zinc Air batteries. Other composite B-2(1:1) and B-3(2:1) due to its higher and moderate thermal stabilities, their electrical conductivities increases and it can find use by the end user for suitable application as per the need in a manufacturing industry.
