The pore volume percent is estimated to be about 49.5% in present work.
The PS-FLG materials possess remarkably high specific surface area and satisfactorily large pore volume.
Table 1 shows the surface areas and pore volume of ACFL120, AC120, ACFL550 and AC550.
Two parameters, the large capillary pore volume and the medium capillary pore volume, were evaluated using multiple regression analysis.
Barrett, E. P., Joyner, L. G. & Halenda, P. P. The determination of pore volume and area distributions in porous substances.
Table 1 Surface area (SBET (m2 g−1)) and pore volume (cm3 g−1) for different acidic supports.
Moreover, the surface area and pore volume of ACFL550 are larger than that of AC550 as shown in Table 1.
BET surface area and pore volume were measured by N2 adsorption and desorption isotherms at liquid nitrogen temperature (−196 °C).
"It shows structural information of what is going on visually, and quantitative numbers that show the distribution of bubbles and the pore volume," she said.
The aggregates have high specific surface area and pore volume.
A pore volume fraction up to approximately 20% was estimated.
