A Chemical Reactor for Hierarchical Nanomaterials with Tunable Structures: A Metal-triggered Reaction in the Confined Heat Chamber |
| 초록 |
A novel protocol for the synthesis of core@shell particles with transformable core structures has been introduced, and its use as a chemical reactor for hierarchical nanomaterials with tunable properties has been demonstrated. A metal, metal/polymer, or bimetallic hollow structure was incorporated into the interior of silica capsules via controlled heat treatment of the inorganic-coated polymer particles. A micrometer-sized capsule was used as a reaction chamber to contain and sustain heat, and metal NPs were used as a controller for the transformation of polymer cores. By varying the thermal conductivities of the metal NPs, it was also possible to confer synthesis of hat-like, UFO-like, or bimetallic hollow structures within the capsule. Furthermore, Pt/Au capsule@SiO2 and Au/polymer@SiO2 showed excellent catalytic properties for the transformation of nitrophenol to aminophenol. This approach could be used to tune the structures and properties of various kinds of polymer matrices. |
