摘　　要：以多壁碳纳米管为载体,用液相还原法制备了Pt/MWNTs催化剂,通过XRD、TEM等技术对催化剂进行了表征,并将所制催化剂组装成燃料电池,以H_2、O_2为反应气,测试了催化剂的性能,结果显示Pt/MWNTs催化剂具有优良的电催化活性。Pt/MWNTs catalysts were prepared by liquid chemical reduction using multi-wall carbon nanotubes as carrier,and XRD and TEM were used to characterize these catalysts. The properties of PEMFC were studied,and the results show that Pt/MWNTs catalysts are better than traditional Pt/XC-72 catalysts.
