Abstract

Holey support: The generation of a porous coating of SiO₂ on Pt-decorated TiO₂ nanofibers enables the preparation of a sinter-resistant catalytic system (see picture). The Pt nanoparticles could resist sintering at temperatures up to 750C in air, as the SiO₂ coating acts as a physical barrier that slows down surface migration, but the system remained catalytically active because of the porous nature of the coating.
