一种低晶面指数Cu2O多面体颗粒的制备方法
摘要：
本发明提供一种低晶面指数Cu2O多面体颗粒的制备方法，该方法可以通过调节铜源的种类、加入碱溶液的量和反应时间来对Cu2O多面体形貌进行准确调控，制备出物相均匀、纯度高、单分散、低晶面指数暴露的Cu2O多面体颗粒；该方法操作步骤少，设备简单，工艺简便，制备所需的原料种类少，降低生产成本，减少环境污染；本发明原理可靠，不需要添加任何表面活性剂，避免表面活性剂残留在某些表面而改变催化反应时的活性中心，便于对Cu2O复合其它材料时的机理进行解释。
摘要（英）：

The invention provides a preparation method for Cu2O polyhedral particles with low indices of crystallographic plane. According to the method provided by the invention, a Cu2O polyhedral shape can beaccurately regulated and controlled by adjusting the types of copper sources, the adding amount of an alkaline solution and the reaction time, so as to prepare the Cu2O polyhedral particles which havea uniform phase and high purity, are monodisperse and have exposed low indices of crystallographic plane. The method provided by the invention has the advantages of a few of operation steps, simple equipment and simple and convenient process; the types of raw materials needed for preparation are few so that the production cost is reduced and the environment pollution is reduced; and the preparation method is reliable in principle and any surfactant does not need to be added so that a condition that the surfactant is remained on certain surfaces and an active center in catalytic reaction is changed is avoided, and a mechanism for compounding Cu2O with other materials is convenient to explain.
