英文摘要: A sulfonic acid functionalized titanium dioxide quasi-superparamagnetic nanocatalyst Fe3O4@SiO2@TiO2-OSO3H with average size of 61 nm and semispherical shape with surface area about 97 m2 g−1 with saturation magnetization 17.7 emu g−1 and the coercivity 9.84 Oe was successfully synthesized. The structure and morphology of the nanocatalyst was characterized by Fourier transform infrared spectroscopy (FT-IR), energy-dispersive X-ray spectroscopy, X-ray diffraction pattern, transmission electron microscopy, field-emission scanning electron microscopy, vibrating sample magnetometer and Brunauer–Emmett–Teller surface area analysis. The catalytic usage of the nanocatalyst was exemplified in synthesis of...
