Cu_(2)O纳米线阵列的制备与表征

Preparation and characterization of Cu_(2)O nanowire arrays

Cu_(2)O纳米线阵列既保留了纳米线长径比高、比表面积大等优点,又具有规模效应及协同效应,在气敏、光伏等领域具有广阔的应用前景。以泡沫铜为基体,通过化学法制备Cu(OH)_(2)纳米线阵列为前驱体,并在N_(2)气氛中采用两步加热法制备Cu_(2)O纳米线阵列,利用X射线衍射(XRD)、扫描电镜(SEM)对Cu_(2)O纳米线阵列结构进行表征。结果表明:只需控制、优化Cu基底的曲率半径和弧度,就能制备出Cu_(2)O纳米线阵列,这为制备Cu_(2)O纳米线阵列薄膜提供了新的思路。

Cu_(2)O nanowire arrays have the advantages of high length diameter ratio and large specific surface area of nanowire,and also have the scale effect and synergistic effect,making them broad application in gas-sensitive and photovoltaic fields.Copper foam was used as matrix,Cu(OH)_(2) nanowire arrays were prepared as precursors by chemical method,and Cu_(2)O nanowire arrays were prepared in N_(2) by two-step heating method.The structure and morphology of Cu_(2)O nanowire arrays were characterized by XRD and SEM.It was found that the preparation of Cu_(2)O nanowire arrays only needed to control and optimize the curvature radius and radian of the Cu substrate,which provided a new idea for the preparation of Cu_(2)O nanowire array films.
