In our previous work (Molecules 2020, 25, 443. ), we described in detail how to calculate the specific surface area and volume fraction. In this paper, the same method was used to calculate the specific surface area and volume fraction, so we did not repeat how to calculator, just added the reference in the manuscript.
Page 6. 199-198 “The specific surface area and volume fraction of pores are calculated, and the results are shown in figure 7.” From the text of the manuscript it is not clear what method was used to obtain the calculated data on the specific surface area and volume fraction of pores.
