制备MCM-41模版剂去除问题。
|
|||
| 制备MCM-41模版剂去除的方法有哪些？一般常用的就是在马弗炉中煅烧，以前记得看过用什么萃取的方法的，但是文献找不到了。有知道这方面的朋友能不能来交流一下。有相关的文献上传上来最好，谢谢！ |

除了焙烧方式，可以参考以下文献(处理对象不一定是MCM－41，但有借鉴意义)： Isothermal template removal from MCM-41 in hydrogen flow Microporous Mesoporous Mater., 2007, 98(1-3): 242-248 Simple removal of oligomeric surfactants and triblock copolymers from mesostructured precursors of ordered mesoporous aluminum organophosphonates Microporous Mesoporous Mater., 2007, 101(1-2): 207-213 Removal of organic templates from mesoporous SBA-15 at room temperature using UV/dilute H2O2 Microporous Mesoporous Mater., 2006, 96(1-3): 413-418 Low temperature oxidative template removal from SBA-15 using MnO(4)(-)solution and carbon replication of the mesoporous silica product J.
