摘要：
A multicore superparamagnetic Ni0.5Zn0.5Fe2O4/SiO2 catalyst support was synthesized by slightly modifying the conventional preparation method, namely, altering the manner of introducing Ni0.5Zn0.5Fe2O4 nanoparticles into TEOS. The modified method resulted in a great increase in specific surface area, saturation magnetization of Ni0.5Zn0.5Fe2O4/SiO2 and better separation in liquid system. The synthesized catalyst supports were characterized by means of X-ray diffraction, N-2 gas adsorption-desorption experiments, transmission electron microscopy and a physical properties measurement system(PPMS).
