Аннотация: Magnetic nickel ferrite/gold hybrid nanoparticles are promising materials for use in medicine, microelectronics, and plasmon-enhanced photocatalysis. The catalytic activity of a hybrid material depends on the composition, morphology, surface charge, and size of the magnetic core. In this work, anion-exchange resin coprecipitation oПоказать полностьюf iron and nickel followed by heat treatment of the prepared hydroxides was used to manufacture nickel ferrite NiFe2O4 nanopowders. Fractional factorial design (FFD 27-4) was used to study the effects of reaction parameters on NiFe2O4 formation. The synthesis under the found optimal conditions yielded powders with an average grain size of 22.7 ± 1.0 nm. NiFe2O4/Au hybrid particles were manufactured by the direct reduction of gold with methionine (α-amino-γ-methylthiobutyric acid). Their formation was proved by optical spectroscopy, transmission electron microscopy, and X-ray photoelectron spectroscopy.
