摘要
SO_4^(2-)/M_xO_y类固体酸催化剂因其催化活性高、选择性好、易分离、无腐蚀性等优点成为近年来环境友好型催化材料之一.综述SO_4^(2-)/M_xO_y类固体酸催化剂的制备及其改性,利用负载模板如分子筛、掺杂金属元素和改变浸酸种类等方法可以改善其微观孔道结构、增加比表面积,提高SO_4^(2-)/M_xO_y类固体酸的热稳定性,改善SO_4^(2-)/M_xO_y类固体酸的催化活性以及重复使用性,并对今后SO_4^(2-)/M_xO_y类固体超强酸的研究方向进行展望.
In recent years, SO4^2-/MxOy solid acid catalysts has become one of the environmental friendly catalysts for its high cat- alytic activity, good selectivity, easy separation and non-corrosiveness. In this paper, the preparation and modification of SO4^2-/MxOy solid acid catalysts are reviewed. The thermal stability, catalytic activity and reusability of SO4^2-/MxOy catalysts can be significantly improved by using molecular sieves as template, doping metal elements and changing leaching acid type to modify the micro pore structure and increase the specific surface area of the catalyst. Finally, the future development for SO4^2-/MxOy solid acid catalysts is pros- pected.
