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 of iron and nickel followed by heat treatment of the prepared hydroxides was used to manufacture nickel ferrite NiFe 2 O 4 nanopowders. Fractional factorial design (FFD 2 7-4 ) was used to study the effects of reaction parameters on NiFe 2 O 4 formation. The synthesis under the found optimal conditions yielded powders with an average grain size of 22.7 ± 1.0 nm. NiFe 2 O 4 /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.
