Adsorption and structural properties of ordered mesoporous carbons synthesized by using various carbon precursors and ordered siliceous P6mm and Ia3d mesostructures as templates
Article Abstract:
A study is conducted on adsorption and structural properties of inverse carbon replicas of two ordered siliceous, P6mm and Ia3d mesostructures by nitrogen absorption, powder X-ray diffraction and transmission electron microscopy. Results show that KIT-6 silica exhibiting 3D bicontinuous network of large channels with interconnecting micropores constitute an excellent template for preparing its faithful inverse replica.

Experimental evidence for pore blocking as the mechanism for nitrogen sorption hysteresis in a mesoporous material
Article Abstract:
The mercury porosimetry experiments are integrated with gas sorption to detect the existence of pore blocking effects during the desorption of nitrogen from a mesoporous sol-gel silica material at 77K. The theory of pore blocking in combination with percolation theory are used to develop various methods of analysis for gas sorption data for the structural characterization of porous media.
