传统酸陛催化反应以稀硫酸为酸催化剂,虽然稀硫酸的催化活性很高,但由于稀硫酸极易腐蚀设备、不易与反应体系分离、易造成环境污染等缺点,如何用固体超强酸取代稀硫酸作为酸催化剂成为了研究的重点.对目前有关磁性固体超强酸的研究主要有SO4^2-/ZrO2/MFe2O4(M=Fe,Co.
SO4^2-/TiO2/Fe3O4 supporting Ni catalyst was synthesized via the sol-gel technology. It is a bifunctional catalyst that could be employed in both metal catalytic and acid catalytic processes and separated by magnetic field. XRD, TEM, and FT-IR were performed on the catalyst with reference to its structure, particle size, acidity, and Ni loading.
