[交流] 大家帮我一下,关于介孔方面的 已有3人参与

有个稿子,有个审稿者给了如下评语:

The authors claimed that the Gd(OH)CO3•H2O has no adsorption-desorption hysteresis in N2 adsorption isotherm, which indicate there is no mesopore. This statement is wrong. Mesoporous silica MCM-41 also has no adsorption-desorption hysteresis but it is a common mesoporous material with very large surface area (ca. 1000 m2/g). The authors could insert a pore size distribution curve in Fig.S4 as in done Fig 3. Then it should be clear there is no peak in the curve.

如果材料没有介孔的话,孔尺寸分布曲线几乎是一条直线吗?

MCM-41没有hysteresis吗?我印象中除了微孔分子筛不出现外,一般介孔材料都会出现的。
