摘要: The interaction of acetic acid vapors with iron-exchanged montmorillonites leads to iron acetate intercalates which upon pyrolysis transform magnetic γ-iron oxide nanoparticles dispersed onto the external surface clay mineral. As these novel composites retain original swelling and cation-exchange properties mineral, synthesis various derivatives is readily attained. X-ray diffraction, electron spin resonance, Mossbauer spectroscopy, measurements, transmission microscopy provide evidence for formation phase also its location in structure.
