摘要(Abstract)：

以Fe为阴极、Ni-Cr合金为阳极,在熔融碳酸盐电解质过程中,采用一步法电解CO2制备蜂窝状单质碳和碳纳米线。利用扫描电子显微镜(SEM)、X线衍射仪(XRD)、透射电子显微镜(TEM)、拉曼光谱仪(RAM)、比表面积测定仪(BET)及激光粒度仪等仪器,分别对碳纳米材料的形貌、晶型结构、比表面积和粒度进行表征。考察电解温度对单质碳形貌的影响,根据计算产碳质量与消耗电荷量的关系,确定最佳电解条件。结果表明:电解温度影响产物的整体形貌及产碳的电流效率,电解温度为850~900K时获得的碳纳米材料形貌呈蜂窝状,电解温度为900~950K时获得的碳纳米材料形貌呈线状。随着电解温度的升高,碳纳米材料的粒径逐渐增加,比表面积逐渐减小。产碳的电流效率随电解温度的升高而降低,在最优电解条件下,电流效率可达82.33%。
