Polyelectrolyte Multilayer-Mediated Chemical Reactor for Hierarchical Nanomaterials with Controllable Properties |
| 초록 |
Specially designed structures as chemical microreactors were prepared for synthesizing nanomaterials with tunable properties. Overall structures were microcapsules containing a movable polymer core. The Au NP-embedded polymer core-in-SiO2 shell structures were formed by controlled heat treatment of PEMPR-Au/SiO2. After calcination of PEMPR-Au/SiO2, gold nanoparticles (NPs) with high mobility under such conditions were homogenously distributed on certain region of polymer particles and it led to the transformation of polymer particles. Selective dissolution of shell materials was able to collect the desired products such as polymer cores. The structures and properties of the metal NP-embedded polymer cores could be also tuned by varying the metal NPs which possess different thermal properties. Among the product materials, Au NP-embedded polymer cores were effectively utilized as nanocatalysts for transformation of 4-nitrophenol to 4-aminophenol. |
