Yolk–shell catalytic nanoreactors with sub‐10‐nm Au nanoparticles and a mesoporous ZrO 2 or TiO 2 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.
