通过水热方法制备得到了含铜元素的碳基微球，并通过控制退火条件使碳基微球中析出不同尺寸的铜纳米、亚微米颗粒。利用粉末X射线衍射（XRD）、扫描电子显微镜（SEM）、透射电子显微镜（TEM）等方法表征了所得的铜、碳复合材料。实验发现，铜颗粒的尺寸随着退火温度的升高而增大，粒径可以在约50～500 nm的尺度范围内实现控制。将不同尺寸的铜纳米颗粒/碳微球复合材料修饰在玻璃碳电极上，制作成为葡萄糖浓度电化学传感电极，并测量了其传感性能和退火条件、铜颗粒尺寸之间的关系。

Carbonaceous microspheres containing copper species were obtained by hydrothermal method and copper particles grew from the carbonaceous microspheres by controlled annealing conditions. The as-obtained products are characterized by X-ray powder diffraction ( XRD) , scanning electron microscopy ( SEM) , and transmission electron microscopy ( TEM) . The particle size could be controlled in the range of about 50 to 500 nm by increasing the annealing temperature. The particles grew in size as the temperature raised. The differently-sized carbon microspheres / copper particles composite were used to modify the glass carbon electrode, and the performances as glucose sensor were tested.
