采用低温水热还原法制备了平均直径为1μm的多孔氧化亚铜八面体。讨论了聚乙烯吡咯烷酮(PVP)和柠檬酸的生长机理及影响因素。然后，将样品用于光催化降解甲基红(MR)。由于产品的3D结构，光催化性能得到了显著提高。我们相信，目前的工作将开启系统探索制备多孔纳米结构的方法，从而在各种应用中找到用途。
Porous cuprous oxide octahedra with a mean diameter of 1 μm have been successfully prepared with high yield via a hydrothermal reduction process at a low temperature. The growth mechanism and the influences of the poly(vinylpyrrolidone) (PVP) and citric acid have been discussed. And then, the samples were used as photocatalytic in the degradation of methyl red (MR). Thanks to the 3D architecture of the product, the photocatalytic performance has been significantly improved. We believe that the present work will open up to systematically explore ways to fabricate porous nanostructures and thus find use in a variety of applications.
