A Library of Nanocrystal‐Inserted Ordered Mesoporous Frameworks with Ultrahigh Density and Spatial Dispersity

Abstract It is a great challenge to integrate incompatible subunits into ordered macroscopic materials with tailored functionalities. Herein, a facile modular assembly strategy is demonstrated to link incompatible colloidal nanocrystals and polymer micelles by using the phenolic resol as the “molecule glue” for the synthesis of nanocrystal‐inserted mesoporous frameworks with diverse functionalities. It is found that the uniform nanocrystals can be inserted into the mesoporous frameworks with outstanding spatial dispersity, even in the case of high incorporation density. This modular assembly route is versatile, a library of nanocrystals with diverse diameters, shapes, and compositions can be integrated into various kinds of mesoporous frameworks (carbon, carbon‐SiO₂, and carbon‐TiO₂ composites). Unprecedently, this strategy also allows the controllable assembly of two, even three types of nanocrystals within the mesoporous frameworks to achieve multiple functionalities. The as‐prepared nanocomposites can simultaneously exhibit catalytic, magnetic, and adsorption properties independently, and show synergistic effects for tandem catalytic applications.
