复合氧化物S_2O_8^(2-)/ZrO_2-SnO_2-SiO_2的制备与研究

Synthesis and Research of S_2O_8^(2-)/ZrO_2-SnO_2-SiO_2 Oxide

固体超强酸作为多相酸催化材料,具有许多传统质子酸催化剂无法比拟的优点,本论文在研究SO_4^(2-)/M_xO_y型固超酸的基础上,采用过硫酸铵溶液作为浸渍剂,选取ZrO_2、SnO_2、SiO_2的复合氧化物,将过硫酸根离子负载在上面,制备出新型S_2O_8^(2-)/ZrO_2-SnO_2-SiO_2固体超强酸催化剂.

Solid superacid is the heterogeneous catalysis material,which has an unmatched advantage of many traditional protonic acid,In this paper,based on the study of SO4^2-/MxOy solid superacid,ammonium persulfate solution was treated as an impregnant,choose the complex oxide of ZrO2、SnO2、SiO2 and load S2O8^2- on it to compound a new S2O8^2-/ZrO2-SnO2-SiO2 solid superacid catalyst.
