|
摘要
以碳纳米管为基底,通过电化学沉积法(i-t)在其上面沉积氧化铜纳米颗粒,形成CuO/CNTs复合材料。采用SEM、TEM对材料进行形貌表征,并对材料进行了LSV、稳定性等电化学性能测试,发现所合成的CuO/CNTs复合材料具有较好的氧析出催化性能。
Copper oxide nanoparticles were deposited on carbon nanotubes by electrochemical deposition(i-t) to form CuO/CNTs composites. Through SEM and TEM, the morphological characteristics of the material were studied, and the electrochemical properties of the material such as LSV and stability were tested. It was found that the CuO/CNTs catalyst had better catalytic properties for oxygen evolution reaction.
