Description:
MW-assisted synthesis of heterocyclic compounds and nanomaterials under benign conditions is summarized. Shape-controlled aqueous synthesis of noble nanostructures via MW spontaneous reduction of metal salts using -D-glucose, sucrose, and maltose will be presented. A general method has been developed that accomplishes the cross-linking reaction of poly (vinyl alcohol) (PVA) with metallic systems such as Pt, Cu, and In; bimetallic systems, namely Pt-In, Ag-Pt, Pt-Fe, Cu-Pd, Pt-Pd and Pd-Fe; and SWNT, MWNT, and C-60. The strategy is extended to biodegradable carboxymethyl cellulose (CMC) composite films with noble nanometals; such metal decoration and alignment of carbon nanotubes in CMC is possible using MW which also enables the shape-controlled bulk synthesis of Ag and Fe nanorods in poly (ethylene glycol). MW process delivers magnetic nanoferrites and micro-pine structured catalysts in water from readily available metal salts. The sustainable generation of nano particles and their applications in catalysis and environmental remediation will be highlighted.
