Synthesis of Titania Nanoparticle Loaded Mesoporous Silica via Layer-by-Layer Assembly and their Photocatalytic Activities |
| 초록 |
Titania nanoparticle-loaded mesoporous silica has been studied as a promising material for the photodecomposition of organic pollutants. However, the synthesis methods and photocatalytic properties have not yet been optimized. In this study, we investigated synthesis methods and their photocatalytic properties for the titania nanoparticle-mesoporous silica (SBA-15) composite materials. Various amounts of titania-loaded mesoporous silicas were synthesized using conventional synthesis method based on sol–gel reactions and layer-by-layer (LbL) assembly method. We examined textural characteristics of composite materials, and further evaluated the photocatalytic performances on the decomposition of sodium dodecylbenzenesulfonate (SDBS) in aqueous solution. We could observe that such catalytic reactions are crucially dependent to the dispersed location of titania nanoparticles. This work could help in design of photocatalytic nanomaterials for environmental applications. |
