Abstract

This work presents the results of a study of the physical-chemical properties of gold nanoparticles (NP) prepared in reverse micellar solutions (RMS) using various ion reduction methods, including self-assembly (SA). The spectra of the electron plasmon resonance of the Au NP in the visible region (λ_max ~ 530 nm) and in the UV region of the spectrum (λ_max ~ 200–220 nm) were recorded by UV–Vis spectrophotometry. In the present work, the kinetics of the primary stages of the formation of Au NPs in RMS using various synthesis methods, including SA, has been studied. Based on the results we obtained, an explanation has been provided for the effect of oxygen (aerobic conditions) on the primary stages of the formation of Au NPs using chemical (Chem) synthesis in the presence of the flavonoid quercetin, and radiation-chemical (RadChem) one based on interaction with intermediate particles of water radiolysis. The formation of Au NPs with optical absorption bands in the UV region and the visible region of the spectrum has been corroborated by the results of electron microscopy.

离子还原和氧效应在各种金纳米颗粒形成方法中的作用，包括自组装

本文介绍了在反胶束溶液(RMS)中使用各种离子还原方法(包括自组装(SA))制备的金纳米颗粒(NP)的物理化学性质的研究结果。用紫外可见分光光度法记录了金NP在可见光区(λmax ~ 530 nm)和紫外区(λmax ~ 200 ~ 220 nm)的电子等离激元共振谱。在本工作中，研究了各种合成方法(包括SA)在RMS中形成Au NPs的初级阶段的动力学。根据我们得到的结果，解释了氧(有氧条件)对在类黄酮槲皮素存在下的化学(Chem)合成Au NPs的初级阶段的影响，以及基于与水辐射分解中间颗粒相互作用的辐射化学(RadChem)合成阶段的影响。在紫外区和可见光区形成了具有光学吸收带的金纳米粒子，电镜结果证实了这一点。
