Abstract

Abstract:

The primary electrochemistry and colloid chemistry are the important components of physical chemistry for undergraduate students. On the basis of the nanostructured metal colloids system, a comprehensive chemistry experiment is proposed, which is about synthesis of nanostructured Ag/Au colloidal sols via the direct electrochemical reduction method with the assistance of a surfactant. In addition to the analysis of typical extinction via the UV-Visible spectroscopy, the cyclic voltammetry method is used to understand the effect of the surfactant and reveal the formation process of metal colloids. Such a comprehensive experiment is efficient to not only promote the understanding on the fundamental knowledge of electrochemistry and colloid chemistry, but also enhance the laboratory skill, which is adopted to the laboratory courses for the students majored in chemistry and related.

Key words: Electrochemistry, Colloid chemistry, Sol, Nanomaterial
