  1. aBET surface area calculated by the method of Rouquerol et al.46.
  2. bExternal surface area calculated by the t-plot method with the KJS correction for the layer thickness49. The volume of pores (V) was calculated using the DFT model.
  3. V1micro and V2micro—micropore cumulative volumes from the DFT approach calculated for micropores with widths smaller than 1 nm and in the range of 1–2 nm; V1meso and V2meso—mesopore cumulative volumes from the DFT approach calculated for mesopores with widths in the range of 2–8 nm and widths larger than 8 nm.
