Abstract

The invention discloses a synthesizing method of a loading flower-shaped nano silver structural material, which is characterized in that a silver plate with high purity is taken as an anode, a platinum film electrode is taken as a cathode, a silver nitrate solution with the concentration of 0.003 to 0.01 mol / L is taken as an electrolytic solution, and the volume of the electrolytic solution is 20 to 100 mL; the range of constant voltage is adjusted to be 50 to 200 mV during electrolytic deposition, and the time of the electrolytic deposition lasts for 2 to 15 minutes; the cathode of the loading nano silver structural material is repeatedly rinsed by deionized water after the reaction, and then dried in nitrogen. The synthesizing method of the loading flower-shaped nano silver structural material realizes the growth anisotropy of crystal, leads the size and the microstructure of the nano metallic structure to be controllable, does not need any addition agent and electrode surface modification, and achieves simple control of appropriate voltage and concentration of the electrolytic solution; the synthesizing method is ultra-simple, and has convenient operation, easy-separated products and high purity and well industrial application prospect.

Description

technical field

[0001] The invention relates to a method for synthesizing nanostructured materials, especially to achieve one-step synthesis of silver nanostructured materials with special morphology and microstructure on the surface of a substrate. This special silver nanostructured material exhibits strong micro-region surface-enhanced Raman scattering effect. Background technique

[0002] It is a very hot topic in the field of nanotechnology research to assemble nanoscale tiny units into regular and ordered structures. Through this "bottom-up" approach, we can not only broaden the application range of nanofunctional materials, but also successfully realize the deviceization of nanomaterials. In recent years, due to the very unique physical and chemical properties of silver nanostructured materials, they have promising applications in fields such as optics, catalysis, surface-enhanced Raman scattering (SERS), and chemical biosensing. Hierarchical silver nanostructures co...
