제목 Facile Synthesis of Sunlight-Driven Hierarchical Au/Ag@CNT Nanophotocatalyst
초록 Our study demonstrates a facile approach for the synthesis of noble metal core-in-carbon nanotubes shell (Au@CNT mesh or Au/Ag@CNT mesh) structures, which can be used as catalysts or visible-light driven photocatalysts for transforming or decomposing toxic materials to desired materials. The metal@CNT structures, submicro-meter sized noble metal cores in the CNT mesh shells, were prepared by synthesizing metal nanoparticles (NPs) and then coating polyelectrolytes/CNTs on polymer colloidal particles using a layer-by-layer self-assembly technique, followed by a heat treatment. Our structures could be promising candidates for visible-light driven photocatalysts for the following reasons: i) their core structures can provide a reactive surface where noble metal can react with toxic materials; and ii) their shell structures can provide mechanical robustness against wear and tear, as well as facile mass transportation due to the mesh structure of the CNT shell.
