An Assembly Route to Inorganic Catalytic Nanoreactors Containing Sub‐10‐nm Gold Nanoparticles with Anti‐Aggregation Properties

Yolk–shell catalytic nanoreactors with sub-10-nm Au nanoparticles and a mesoporous ZrO2 or TiO2 shell are prepared from monodisperse hydrophobic Au nanoparticles through an assembly approach (see image). The nanoreactors demonstrate both a remarkable catalytic activity and anti-aggregation properties upon thermal treatment and recycling.
