000151259 5203_ $$aMechanically stable 3-D pellets made of mesoporous SBA-15 silica fibers containing highly dispersedplatinum nanoparticles have been successfully synthesized with the aid of a sacrificial polyacrylamidenetwork using a gel-casting deposition technique. The pellets exhibit a hierarchical porosity, with spacesof 3 microns among the silica fibers, and a core–shell distribution of Pt, with an outer Pt-rich layer of 450microns accounting for over 73% of the Pt. Both factors (hierarchical structure and concentration of thecatalyst on the outer pellet surface) facilitated reactant access to the catalyst centers, and as a consequencean excellent catalytic activity toward the total oxidation of n-hexane, used as a VOC model. There was nomeasurable loss of activity after 70 h on stream and the subsequent examination of the catalyst revealedthat interparticle coalescence of Pt nanoparticles was largely prevented due to the encapsulation of thenoble-metal particles within the silica mesochannels.
