A new and efficient top-down protocol has been developed for production of nanomaterials from waste metal precursors using DMSO/ HNO3/ NaOCl as a strong oxidizing agent. Fe-C-O-Mo nanorods were prepared by this method from screw precursor and used as an efficient magnetic catalyst for multicomponent reactions. [Display omitted] •A new approach for the top-down production of nanoparticles has been developed.•The mixture of NaOCl, DMSO, and HNO3 act as a strong oxidizing agent for metal alloys.•NaOCl/ DMSO/ HNO3 could be efficiently transformed a cheap screw to nanorods.•The prepared nanorods demonstrated excellent catalytic activity toward multicomponent reactions. A cheap screw was used for the preparation of the magnetic Fe-C-O-Mo alloy nano-rods through a chemical decomposition; a top-down approach to synthesis of NPs. The decomposition was performed in the presence of a mixture of DMSO, NaOCl, and HNO3 as an extraordinary oxidizing-corrosive agent. Due to magnetic property of the screw (Fe-alloy), the resultant alloy is magnetic. Magnetic Fe-C-O-Mo alloy nano-rods were applied toward efficient preparation of Hantzsch dihydropyridine and Biginelli dihydropyrimidone compounds under moderate conditions. In following, their kinetics were studied and compared. Characterization and recyclability of the catalyst were also studied.
