| One-Dimensional CuO Nanorods: Preparation by Microemulsion Homogeneous Precipitation and Structure Characterization | |
| 摘要: 以CuSO4和NH3·H2O为原料，采用微乳-均匀沉淀耦合法制备了一维CuO纳米棒。用XRD、SEM、TEM、HRTEM和FTIR对产物的结构和形貌进行了表征。结果表明：产物为单斜晶相结构的CuO纳米棒，内部具有孔洞结构，其直径为40～110 nm，长度为800～3 000 nm。可通过改变水核比(ω)、反应物的浓度、反应时间、反应温度等条件实现对CuO纳米棒形貌和尺寸的调控。探讨了可能的反应机理，并用热分析方法考察了CuO纳米棒对高氯酸铵(AP)分解的催化作用。 | |

| Abstract: By using CuSO4 and NH3·H2O as raw materials, the 1-D CuO nanorods were prepared by the couple method of microemulsion with homogeneous precipitation. The morphology and structure of products were characterized by XRD, SEM, TEM, HRTEM and FTIR. The results indicate that the as-prepared CuO nanorods with a diameter of 40～110 nm and a length of 800～3 000 nm have a monoclinic structured single-crystalline and the inner structure is porous. The size and morphology of CuO nanorods can be controlled by changing the ratio of water to surfactant(ω), the concentration of reactants, reaction time and reaction temperature. The possible mechanisms for the formation of CuO samples are discussed. The catalysis of CuO nanorods on NH4ClO4(AP) decomposition was investigated by thermal analysis. | |
