2.2.3.2 PSD Analysis from the Nitrogen Adsorption

Due to the tensile strength effect, the pore size distribution analysis which can be estimated from the desorption curve, will be limited to 4–5 nm which cannot describe the pore structures accurately. So, the adsorption branch will be chosen for the PSD analysis. Figure 2.20 shows the pore size distribution of the samples based on the DFT theory. The PSD curve of all samples exhibited the multimodal characteristic with several volumetric maxima. The pore structures were analysed and the following observations were reached:
