A Sinter‐Resistant Catalytic System Based on Platinum Nanoparticles Supported on TiO₂ Nanofibers and Covered by Porous Silica

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 750 °C 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.
