Large Scale Solid-state Synthesis of Catalytically Active Fe₃O₄@M (M = Au, Ag and Au-Ag alloy) Core-shell Nanostructures.

ABSTRACT: Solvent-less synthesis of nanostructures is highly significant due to its economical, eco-friendly and industrially viable nature. Here we report a solid state synthetic approach for the fabrication of Fe₃O₄@M (where M = Au, Ag and Au-Ag alloy) core-shell nanostructures in nearly quantitative yields that involves a simple physical grinding of a metal precursor over Fe₃O₄ core, followed by calcination. The process involves smooth coating of low melting hybrid organic-inorganic precursor over the Fe₃O₄ core, which in turn facilitates a continuous shell layer post thermolysis. The obtained core-shell nanostructures are characterized using, XRD, XPS, ED-XRF, FE-SEM and HR-TEM for their phase, chemical state, elemental compositio
