Cyclic microwave-assisted synthesis of CuFeS2 nanoparticles using biomolecules as sources of sulfur and complexing agent

Copper iron sulfide (CuFeS2) nanoparticles were successfully synthesized by a 300 W cyclic microwave radiation, exposing onto ethylene glycol containing Cu(CH3COO)2, FeCl3 · 6H 2O or FeCl2 · 4H2O and L-cysteine biomolecules. X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SE...
