将Pd纳米颗粒负载在功能化的多壁碳纳米管(MWCNTs)上制备出Pd/MWCNTs催化剂。应用TEM、XRD对其进行表征,并利用循环伏安(CVs)、时间电流法检测其对碱性溶液中甲醇的催化活性。结果表明,Pd纳米颗粒高分散在功能化的多壁碳纳米管上,在碱性溶液中Pd/MWCNTs催化剂对甲醇显出了高的催化活性和稳定性。
Pd / MWCNTs catalysts were prepared by loading Pd nanoparticles on functionalized MWCNTs. The catalysts were characterized by TEM and XRD. Cyclic voltammetry (CVs) and time-current measurements were applied to determine the catalytic activity of methanol in alkaline solution. The results show that the Pd nanoparticles are highly dispersed on the functionalized MWCNTs. Pd / MWCNTs catalysts show high catalytic activity and stability to methanol in alkaline solution.
