The mean pore diameter increased by 40% when samples were treated with H2O2 for 48 h.
The asymmetric support consists of five layers, each one characterized by a specific thickness and mean pore diameter.
These systems showed lower mean pore diameter and scarcer formation of zeolite structures when compared to KOH/BFS systems.
The specific surface area of these catalysts is about 84 m2 g−1, with a mean pore diameter of 2.5 nm.
The hydrogel with equal concentration of oxidized polysaccharides and gelatin displayed the highest degree of crosslinking and the lowest value of mean pore diameter.
The mean pore diameter could be regulated from 5 μm to 60 μm by varying the freezing temperature through the cooling rate.
A monotonic correlation between temperature and mean pore diameter was detected being the higher the activation temperature the lower the mean pore width of AC.
The synthesized particles had non-symmetrical 3-D wormhole-like mesostructure, spherical morphology, and a mean pore diameter between 53 and 59 Å.
After aging, a decrease in surface area and pore volume was observed, as well as an increase in mean pore diameter.
The mean pore diameter of these silica films corresponds to the dimension of the polymer domains observed in the pristine hybrid films.
For the non-wetted membranes (mean pore diameter of 0.1 μm), the Knudsen and continuum diffusion must be taken into account.
