Rattle-Typed Hierarchical Spheres (Au/Ag@AgX@SiO2) for Nanophotocatalyst |
| 초록 |
A novel protocol for the synthesis of core@shell particles with Ag or Au/Ag core structures has been introduced, and its use as a photocatalyst for decomposing toxic materials has been demonstrated. A monometallic Ag or bimetallic Au/Ag core was incorporated into the interior of SiO2 capsules via controlled heat treatment of the metal nanoparticle/SiO2-coated polymer particles. By appropriate treatment, it was possible to transform the Ag or Au/Ag core into the Ag@AgX or Au/Ag@AgX core within the SiO2 capsules (Ag@AgX@SiO2 or Au/Ag@AgX@SiO2). This novel method for core@shell particles is useful for incorporating AgX with plasmonic materials into the capsules materials. To the best of our knowledge, synthesis and use of core@shell-typed photocatalysts have not yet been reported. The Ag@AgX@SiO2 or Au/Ag@AgX@SiO2 photocatalysts showed excellent catalytic properties for the decomposition of toxic substances. |
