A 3D-TEM study of the shape of mesopores in SBA-15 and modified SBA-15 materials.
The mesopores in SBA-15 are curved on a mesoscopic length scale and even more so in the case of modified SBA-15, which implies that using the particle size of these types of materials in diffusion studies may strongly underestimate the path length relevant for intraparticle diffusion.
