Morphological effect of noble metal nanostructures on catalytic reduction of 4-nitrophenol |
| 초록 |
2D Au nanostructures and 0D Ag nanoparticles were loaded on the template surface and used as catalysts for reduction of 4-nitrophenol. 2D Au nanostructures with controlled edge length and thickness were synthesized into three different polygonal shapes containing smooth/jagged-edged and single/multiple-layered nanosheets. We successfully fabricated a robust and reusable catalyst by incorporating 2D Au nanostructures in a cellulose paper as a flexible substrate through the monolayer assembly and transfer method. In addition, we used Ag NPs as another catalyst material. It was grown without aggregation on the surface of the Fe3O4 coated with PS for reduction of 4-nitrophenol. Despite their micrometer-scaled lateral dimension, the high catalytic activity of the 2D Au NSs was observed in the reduction reaction of 4-nitrophenol to 4-aminophenol in the presence of NaBH4. Also, the nanometer-scaled 0D Ag NPs showed high catalytic activity for reduction of 4-nitrophenol to 4-aminophenol. |
