Environment-friendly synthesis method of 1D chain structure nano particles

Abstract

The invention discloses an environment-friendly synthesis method of 1D chain structure nano particles, and aims to provide an environment-friendly synthesis method of 1D chain structure nano particles by one step via utilizing myricetin as a reducing agent and a capping agent under the condition of no mold plate. The method is mild in reaction condition, is simple and convenient to operate, and is low in environment pollution. The technical scheme is that the environment-friendly synthesis method sequentially comprises the following steps: (1) weighing metal salt and myricetin respectively according to substance ratio of (2-10) to 1; (2) dissolving the metal salt weighed in the step (1) into water so as to prepare a metal salt aqueous solution, and dissolving myricetin into a solvent to prepare a myricetin solution; and (3) mixing the metal salt aqueous solution and the myricetin solution, adjusting the pH value to 8-12, reacting at room temperature for 2-30 minutes so as to obtain the 1D chain structure nano particles. The invention belongs to the technical field of nano material preparation.

Problems solved by technology

[0004] The synthesis of traditional 1D chain-like metal nanoparticles is almost always based on template assembly. However, regardless of the soft template used in solution to provide recognition or interaction with ligand molecules, or the hard template based on solid surface , are all necessary for the assembly process of the spatial structure of metal nanoparticles, but the template method has defects such as chemical reagent pollution and cumbersome reaction steps, and its products are difficult to achieve large-scale practical applications, and its application in the field of biomedicine is also limited.
