最近投了一篇文章,我本身是做电化学,关于氮气吸附脱附的相关只是几乎不懂,也只看过几篇文献的这部分,只能照葫芦画瓢。下面是我文章的这部分,以及审稿人意见,求大神指点该如何回复这个问题。谢了!
我文章中的描述部分:
The Nitrogen adsorption–desorption isotherm of the ordered MCNAs exhibits type IV characteristics (Fig. 3), which is indicative of the presence of relatively large pores in the sample. The BET surface area and total pore volume of the ordered MCNAs are 960 m2 g−1 and 1.598 cm3 g−1, respectively. The mesopore size distribution shown in Fig. 3 (inset) indicates that the mesopore sizes of the ordered MCNAs are dominantly distributed between 3.0 nm and 5.0 nm with a peak value at ~ 3.9 nm. The average pore diameter determined by BJH method is 8.8 nm.
审稿人的修改意见:
Nevertheless, the characterization of the mesoporous structure of carbon nanofiber arrays is still not convincing. The author described that the mesopores of ordered MCNAs are mainly centered at ~3.9 nm (page 5, line 56). However, the nitrogen adsorption curve (Figure 3) indicates the presence of mesopores with broad size distribution (a sharp capillary condensation step does not appear). TEM images (Figure 2C) does not give clear evidence for the uniform mesopores, either. In my opinion, sharp pore size distribution presented in inset of Figure 3 might be calculated from a desorption curve. The author should surely confirm whether the pore size distribution was derived by using the adsorption isotherm.
