Abstract

The possibility of reduction and stabilization of gold nanoparticles by chitosan in carbonic acid solutions under high CO₂ pressure has been considered for the first time. To analyze the nature of the interaction of the system components, UV-visible and IR spectroscopies have been used. The morphology and size of chitosan-stabilized gold nanoparticles have been determined using TEM. It has been revealed that the stabilization of gold nanoparticles occurs with the participation of amino groups. It has been shown that small spherical nanoparticles are stabilized at a sufficiently high concentration of gold in the solution.

高CO 2压力下碳酸溶液中壳聚糖稳定金纳米颗粒的原理

摘要

首次考虑了在高CO ₂压力下，壳聚糖在碳酸溶液中还原和稳定金纳米颗粒的可能性。为了分析系统组件相互作用的性质，已使用了紫外可见光谱和红外光谱。壳聚糖稳定的金纳米颗粒的形态和尺寸已使用TEM确定。已经揭示了金纳米颗粒的稳定在氨基的参与下发生。已经表明，在溶液中足够高的金浓度下，小的球形纳米颗粒被稳定。
