摘要:

为了让学生了解纳米材料的一般合成方法及灌输纳米材料的可控化合成理念,采用绿色合成方法液相还原法制备不同颜色的Cu2O微米粒子。该实验以葡萄糖为还原剂,通过班氏试剂在碱性条件下进行反应,成功合成了不同尺寸和形貌的氧化亚铜溶胶,用生物显微镜对样品进行形貌表征,通过自制立方晶系晶体的形状模型探讨Cu2O形貌控制机理,从而实现对其形貌和粒径的有效控制,并考查了Cu2O作为可见光催化剂对有机染料亚甲基蓝的降解性能。本实验涉及纳米材料的合成、调控及应用,有利于培养学生的观察能力、分析问题和解决问题的能力,同时,纳米材料应用于有机染料的污水处理中,对培养学生的环保意识和专业强国意识也有很大帮助。

Abstract:

In order to let students understand the general synthesis method of nanomaterials and instill the concept of controllable synthesis of nanomaterials, the green synthesis method is used to prepare Cu2O microparticles of different colors by the liquid phase reduction method. In this experiment, glucose was used as the reducing agent, and the Bancol reagent was used to react under alkaline conditions. The cuprous oxide sol of different sizes and morphologies was successfully synthesized, and the morphology of the sample was characterized by a biological microscope. The control mechanism of Cu2O morphology was explored by shape model of Cu2O to realize the effective control of the morphology and particle size. The degradation performance of Cu2O as a visible light catalyst on the organic dye methylene blue was evaluated. This experiment involves the synthesis, control and application of nanomaterials, which is conducive to cultivating students' ability to observe, analyze and solve problems. At the same time, the application of nanomaterials to the sewage treatment of organic dyes will help cultivate students' environmental awareness and professional power.

Key words: Cuprous oxide, Biological microscope, Controllable synthesis, Photo-catalysis, Methylene blue
