Chemical synthesis and characterization of zinc, iron and carbon-based nanoparticles and their nanocomposites
Keywords:
Nanoparticles, nanocomposites, grapheme oxide, zinc oxide, magnetite, chitosanAbstract
The wet chemical approach (an aspect of the bottom-up method) was used to synthesize zinc oxide, magnetite and graphene oxide, graphene oxide/magnetite and chitosan/magnetite nanoparticles and their nanocomposites. The synthesized particles were characterized by FESEM/EDX, FT-IR and XRD techniques. Zinc oxide was obtained with a crystallite size of 9.0 nm. The synthesized magnetite particles had a crystallite particle size of 6.4 nm. Crystallite sizes obtained for GO, GO-magnetite and chitosan-magnetite were 7.9, 7.1 and 11.2 nm, respectively. The synthesized composite did not display any phase change in the magnetite
