Abstract

Trimanganese tetraoxide (Mn3O4)-silver (Ag) nanocomposites have been synthesized by seed-mediated growth of manganese oxide by alkaline hydrolysis of manganese precursor on preformed silver nanoparticles at water/n-heptane interface. The morphology of the nanocomposites has been varied by individual addition of five size-selective silver nanoparticles for the evolution of the manganese components. Varieties of spectroscopic and microscopic techniques have been used to characterize these materials. Now, the efficacy of these as-synthesized nanocomposites has been demonstrated towards the sensing of various hazardous volatile organic compounds, exhibiting high sensitivity to ethanol compared to other components. Moreover, the structure-function relationship of the Mn3O4-Ag nanocomposites upon variation of the size of silver particles towards the sensory activity of ethanol has been elucidated.
