| 摘要: 采用一步法成功制备出多孔氧化铜空心微球，用SEM、XRD和FTIR对制得的样品进行了表征。研究发现，碳源、反应温度、反应时间、CuSO4浓度等实验条件在多孔微球的制备过程中起着重要作用。在实验结果的基础上，提出了多孔氧化铜空心微球的形成机理。制备的多孔氧化铜空心微球的比表面积为409 m2·g-1，平均孔径为3.15 nm，总孔体积为0.256 cm3·g-1, 这种空心微球具有量子尺寸效应并对罗丹明B有较高的光催化性能。 |

| Abstract: Porous copper oxide (CuO) hollow microspheres were fabricated via a one-step method. The products were characterized by SEM, XRD and FTIR. The carbon source, hydrothermal temperature and time and the concentration of CuSO4 play crucial roles in controlling the morphology of the title material. A formation mechanism was proposed based on the characterization results. The BET specific surface area of the hollow spheres is 409 m2·g-1, the average pore size is 3.15 nm, and the total pore volume is 0.256 cm3·g-1. The material exhibits a quantum size effect in UV spectrum and higher photocatalytic activity for degradation of rhodamine B (RhB) aqueous solution. |
