    • 　　因為有金銅奈米空球的幫助下使我們可以成功的在溶液相中製備出像花形狀的Cu2(OH)3Cl奈米結構。奈米花是一種三維的奈米結構，其是由數十片奈米板所組裝而成，大小大約是幾百個奈米，而金銅奈米球在製備奈米花上扮演著非常重要的角色。我們利用SEM和TEM去觀察金銅中空奈米球與奈米花的形狀與結構，利用HR-TEM, SAED, EDX和XRD去鑑定實驗中所製備的中空奈米球與奈米花的成份。我們做了一系列的實驗去探討奈米花的形成機制，這些實驗包括了在不同反應時間所得到的奈米花形態、在反應中添加保護劑與在通Ar氣體和通氧氣的情況下進行反應所得的結果。最後我們利用一種陽離子型的界面活性劑去分離金銅中空奈米球與奈米花，達到純化的目的

    　Flower-like nanostructures of botallackite Cu2(OH)3Cl have been synthesized in the solution with the aid of Au-Cu hollow nanospheres. The nanoflowers are three-dimensional nanostructures with several hundreds nanometers in size and contain tens of self-organization layered petals. Formation of botallackite Cu2(OH)3Cl nanoflowers was strongly associated with the presence of Au-Cu hollow nanospheres. The morphologied and composition of hollow and nanoflowers have been characterized by SEM, TEM, HR-TEM, SAED, EDX and XRD. We had controlled the time of reaction to get the time-dependent evolution of nanoflowers；and gone on adding protective agent experiments , in argon condition and in oxygen condition experiment to discuss the nanoflower’s formation mechanism. Finally, we utilized a cationic surfactant to separated hollow nanospheres and nanoflowers.
