Hydrothermal synthesis of nanocrystalline MxZn1−xFe2O4 (M=Ni, Mn, Co; x=0.40–0.60) powders

Abstract A series of nanocrystalline M x Zn 1− x Fe 2 O 4 (M=Ni, Mn and Co; x =0.40–0.60) powders have been successfully prepared via hydrothermal process and characterized by XRD, TEM and IR techniques. The effects of reaction temperature and the initial pH value of the starting suspension solution on the particulate properties such as the particle size and morphology are discussed. IR spectra indicate that there are no hydroxyl in as-prepared Ni x Zn 1− x Fe 2 O 4 and Co x Zn 1− x Fe 2 O 4 powders, while there are obvious hydroxyl adsorption on the IR spectrum of Mn x Zn 1− x Fe 2 O 4 powder.
