Abstract

The experimental published data on SBA-15 microporosity was interpreted using a size effect approach. This approach regards the wall micropores of SBA-15 material as stress-induced defects in its pores walls. It was shown that the microporosity is the function of the ratio of the pore wall thickness to pore diameter-the characteristic parameter representing the size of nanotubular silica pores. This suggests that the size effect plays an important role in the microporosity formation and supplements the template-induced microporosity related to the partial occlusion of the PEO chains in silica matrix.
