TEOS, phenol-formaldehyde resin and ethyl alcohol were mixed and gelled at room temperature. Afterward, the gel was dried and submitted to thermal treatment at high temperature (1550°C) in a strongly reducing atmosphere and transformed into a composite of general formula SiO2-C. This composite consists on an amorphous porous silica network intercrossed with another carbon network that has carbonaceous microdomains of high activity; this new material has a sharpened pore size distribution near 1000diameter mainly assigned to the silica network. Both mentioned networks are self supported and independent among them, so one from the other can be isolated without losing the original shape and volume of the starting composite; then this new material has the property of generating two other different porous solids. The new composite was characterized by: LOI, XRD, IR, BET surface area, pore size distribution and SEM. Its adsorption rate was tested with methylene blue solutions by using different techniques, and the results were compared with those obtained for a commercial high performance activated carbon. Experiments with different gelling and drying temperatures were performed in order to control the range in which the composite shows the sharpened pore size distribution. The catalytic activity was tested and compared on FISCHER-TROPSCH process (hydrogenation of CO) on doped iron composite and on doped iron isolated carbon network. Other potential uses of the new composite are presented.
