紫外/臭氧法用于脱除有序介孔材料SBA-15中有机模板剂.该方法是一种非加热光化学降解法,简单、易操作,可在温和条件下彻底除去SBA-15中三嵌段共聚物有机模板剂P123.通过XRD,TEM,FT-IR和BET等对SBA-15经不同方法脱除模板剂前后的详细表征,表明紫外/臭氧法在彻底脱除SBA-15中有机模板剂后,保留了很好的骨架有序性,比表面积更大,孔道更加开放,克服了高温焙烧脱除模板剂造成的孔道收缩.
The UV / Ozone method is used to remove the organic templating agent in the ordered mesoporous material SBA-15. This method is a non-thermal photochemical degradation method that is simple and easy to operate and can completely remove the trimeris Section copolymer organic template P123. The detailed characterization of the SBA-15 by different methods before and after the removal of the template by XRD, TEM, FT-IR and BET showed that the UV / ozone method completely removes the organic template After the agent, retains a good framework of the order, larger specific surface area, more open channels to overcome the high temperature roasting to remove the template caused by the contraction of the channel.
