摘要/Abstract

摘要：

采用T型微混合器通过沉淀法，以氯化铜为铜源，氢氧化钠为沉淀剂，抗坏血酸为还原剂制备出了立方体氧化亚铜纳米颗粒。考察了进料流量、氢氧化钠浓度、抗坏血酸浓度和温度对产物氧化亚铜的形貌、粒度及其分布的影响。采用X射线衍射、场发射扫描电子显微镜和紫外可见分光光度计对其进行表征。结果表明，随着进料流量的增大、氢氧化钠浓度的减小、抗坏血酸浓度的增加和温度的提高，所制备的氧化亚铜颗粒的平均粒径减小、粒度分布变窄。

关键词: T型微混合器, 沉淀, 氧化亚铜, 纳米粒子, 粒度分布

Abstract:

A facile controllable route for preparing cubic cuprous oxide (Cu₂O) nanoparticles in T-shaped micro-mixer was developed by precipitation technique using copper chloride as copper source, sodium hydroxide as precipitant and ascorbic acid as reducing agent. The influences of feed flow rate, sodium hydroxide concentration, ascorbic acid concentration and temperature on morphology, size and size distribution of Cu₂O nanoparticles were investigated by X-ray diffraction (XRD), scanning electron microscope (SEM) and ultraviolet-visible spectrophotometry (UV-Vis). The results showed that size of Cu₂O particles became smaller and size distribution became narrower with the decrease of sodium hydroxide concentration and the increase of feed flow rate, ascorbic acid concentration and temperature.

Key words: T-shaped micro-mixer, precipitation, cuprous oxide, nanoparticles, size distribution
