| 摘 要： | 利用1ChCl∶2Urea低共熔溶剂作为电解质,以单质铜作为阳极,钛片作为阴极,草酸(H2C2O4·2H2O)作为添加剂,在恒电流密度下电解制备出树枝状超细铜粉。用电化学工作站对1ChCl∶2Urea]/0.1 mol·L-1 H2C2O4·2H2O低共熔溶剂体系进行了相关的电化学测试。研究了电解温度、电流密度及草酸浓度对电解所得铜粉的粒度、电流效率和直流电耗的影响;利用扫描电镜和激光粒度仪分别对铜粉的形貌和粒度进行了测试表征。结果表明:优化工艺条件为控制温度在80℃,电流密度为8.6mA·cm-2以及草酸浓度0.10mol·L-1的条件下,可电解得到粒度小于15μm的树枝状超细铜粉,电解过程的电流效率高达95.6%,电耗为1746kW·h·t-1。
