摘要： 利用水热法制备得到片状的碱式硝酸铜,并将其作为催化剂前躯体，分别以氢气和乙炔作为预处理气体和碳源气体,通过化学气相沉积法制备得到了碳纤维阵列。利用扫描电镜和X射线粉末衍射仪对催化剂前驱体和碳纤维的形貌结构和化学组成分别进行了表征和分析。实验结果表明:氢气预处理过程提高了催化剂前驱体热解产物的催化活性，而反应温度的升高则可提高碳纤维阵列的生长速度。

Abstract: In this article, cupric nitrate with platelike structure was produced by a hydrothermal method, and then was used as catalyst precursor to synthesize carbon fiber arrays by chemical vapor deposition method (CVD), in which hydrogen and acetylene were employed as pretreatment gas and carbon source gas, respectively. The morphology and compositions of catalyst precursor and carbon fibers were characterized and analyzed by scanning electron microscopy (SEM) and Xray diffraction spectrometer (XRD). Experimental results demonstrate that hydrogen pretreatment enhanced the catalysis activity of catalyst precursor heat decomposed product, and high reaction temperature can lead to high growth rate of carbon fiber arrays.

Key words: carbon fibers; cupric nitrate; chemical vapor deposition; array
