Synthesis and catalytic activity of monodisperse gold–mesoporous silica core–shell nanocatalysts

Activity Enhancement upon the Incorporation of Titanium: Au@Ti–SiO₂ Core–Shell Nanocatalysts for the CO Oxidation Reaction

Active and Stable: Incorporating Ti
into the Au@SiO2 core-shell
nanoparticle drastically improves
the CO oxidation activity at room
temperature. The core-shell
morphology makes the catalyst
extremely stable for several catalytic
cycles.
