Abstract A novel and flexible strategy involving hydrothermal transformation of guest‐incorporated zeolite‐seeded mesoporous silica spheres was proposed to prepare guest‐encapsulated hollow zeolite three‐dimensionally (3D) ordered macroporous monoliths. The guest species that were pre‐incorporated into the mesopores could be spontaneously encapsulated inside formed shells by consuming nutrition original cores during process. wide range materials with a size ranging from nanometers micrometers, e.g., Ag PdO nanoparticles, carbon polymer micrometer successfully both discrete 3D Such are expected find variety applications such as catalysis, adsorption, microreactors for their special structures active zeolitic porous shell outside.
