摘　　要：Cu2O作为一种重要的半导体化合物在传感器、光催化和锂离子电池等领域有着重要的应用价值。本文在没有使用任何表面活性剂情况下,直接利用氧化铜片的方法水热合成形貌多样的Cu2O纳米结构,如八面体,三叉状,线状结构等。通过调整生长参数,详细研究了反应物浓度,反应温度,反应时间等对Cu2O形貌演化产生的影响。Cu2O, as an important semiconductor compound, has many important applications in sensors, photocatalysis, and some other fields such as lithium-ion batteries. In this paper, in the absence of any surfactants, Cu2O nanostructures with diverse morphologies such as the octahedron, the tripod-like, wirelike structures were synthesized by direct oxidation of copper foil using a hydrothermal synthesis method. By adjusting the growth parameters, a detailed study was done about the effect of the reactant concentration, reaction temperature and reaction time on the morphology evolution of Cu2O. This work will play an important role in the control- lable synthesis of Cu2O nanostructures and the corresponding property and devices.
