用氯化醇钛盐[Ti(i-OC_3H_7)_nCl_(4-n),n=1—2]丙酮溶液负载于SiO_2的表面反应法制备了骨架型、表面键联型和负载型三种类型的TiO_2-SiO_2(TSO)表面复合物,并用红外光谱法研究了它们的表面结构状态及其对CO的化学吸附性能,得出了制备这些表面复合物的适宜方法和条件。
Three kinds of framework type, surface bonding type and loading type were prepared by surface reaction of titanium alkoxide [Ti (i-OC_3H_7) _nCl_ (4-n) TiO 2 -SiO 2 (TSO) surface composites were synthesized and their surface structures and chemisorption properties to CO were studied by infrared spectroscopy. The suitable methods and conditions for the preparation of these surface composites were obtained.
