摘要
用MgCl_2水溶液等体积浸渍SiO_2载体的表面反应方法,制备了键联型和骨架型MgO-SiO_2(MSO)表面复合物,利用红外光谱法(IR),研究了它们的表面结构状态及其对CO和CH_2=CH_2的化学吸附性能,讨论了MSO表面复合物的制备过程化学。
Skeleton type MgO-SiO_2(MSO) surface compounds were prepared by impregnating silica with an aqueous solution of MgCl_2, followed by surface reaction, hydrolysis with aqueous ammonia and calcination at 550℃. The surface-structure and CO and CH_2=CH_2 chemisorption properties of MSO samples have been characterized by IR techniques. The chemistry of the preparation process of these compounds has been discussed.
