A Generic Method for Preparing Hollow Mesoporous Silica Catalytic Nanoreactors with Metal Oxide Nanoparticles inside Their Cavities

We report a facile and generic method for the synthesis of hollow mesoporous silica nanoreactors (HMSNs) with small‐sized metal oxide nanoparticles (NPs) inside their cavities. They were made by deposition of silica onto metal‐containing charge‐driven polymer micelles and subsequent calcination. The...

Description
Summary:We report a facile and generic method for the synthesis of hollow mesoporous silica nanoreactors (HMSNs) with small‐sized metal oxide nanoparticles (NPs) inside their cavities. They were made by deposition of silica onto metal‐containing charge‐driven polymer micelles and subsequent calcination. The micelles consist of 1) negatively charged supramolecular polyelectrolyte chains of bis‐ligand‐bound metal ions, and 2) water‐soluble, neutral/positive diblock copolymers. Owing to the facile coordination between transition‐metal ion and the employed bidentate ligand, a series of HMSNs with
