2000年的那篇提到了MCM-41合成的C-41...

The structure of SBA-15 consists of the
hexagonal arrangement of cylindrical mesoporous tubes 9 nm in
diameter, which is similar to the structure of the honeycomb-like
MCM-41 silica except for random interconnection of the tubes
by micropores present in the pore walls.

这是2000年的JACS中的一句话。这句话的意思是说虽然SBA-15和MCM-41有完全一样的由柱状孔堆积而成的二维六方结构(就像蜂窝煤一样的结构),但不同之处在于SBA-15的柱状孔之间有微孔连接(即孔壁内有微孔),而MCM-41没有这种特点。所以SBA-15的介孔孔道之间是实际是连续的,只有这样才能复制介孔碳。
给你看个示意图就明白了:

还有现在软模板法合成已经很成熟了,干嘛还要用硬模板法,可以参考我的文章做,是可以大批量合成高度有序介孔碳最简单的方法。

还有这句话
It is interesting that the hexagonal structural order is retained in CMK-
3, while a featureless XRD pattern is obtained when carbon is
synthesized using MCM-41 silica. This is because the main
mesoporous channels in SBA-15 are interconnected through
micropores inside the walls of the main channels, while the MCM-
41 channels are not interconnected. In the case of MCM-41 silica,
carbon infiltration leads to the formation of carbon rods that are
not bonded to each other.

ryoo从未用mcm41做出过介孔碳,他第1篇文章发在jpcb上,用MCM48,   第2篇是jscs用sba15,第3篇nature用Al-SBA-15.  我建议你多看看文献再做。
...

请问能把这两篇文献链接发给我吗
