A Novel Approach for Controlling Structure and Size of AgX Nanostructures and Its Application for Visible light-Driven Photocatalyst |
| 초록 |
Ag/AgX (silver/silver halide) has been supposed to be new visible light photocatalytic materials due to its good sensitivity to sunlight. Herein, we report a novel approach for controlling structure and size of AgX structures. We synthesize CTAB-decorated AgBr microplates (MPs) that are obtained by mixing silver precursor with hexadecyltrimethylammonium bromide (CTAB) under controlled conditions. By appropriate polyelectrolytes (PEs) coating, it is able to transform structure of AgBr MPs into submicrometer-sized spherical or cubic shape with controlled sizes. We believe that the PEs which possess certain types of functional groups are the crucial factors that control the structure and size of the AgBr MPs. The size and shape-controlled AgBr cubic NPs can be used as plasmonic photocatalysts for the degradation of methylene orange (MO) dyes that are well known for toxic substances under sunlight irradiation. |
