| 摘 要： | 将萘-1-亚甲基膦酸通过π-π堆积作用修饰在多壁碳纳米管(MWCNT)上，然后制备了MWCNT载Pd(Pd/MWCNT)催化剂。 利用Pd和HAuCl4间的置换反应制得MWCNT载Pd-Au(Pd-Au/MWCNT)催化剂。 透射电子显微镜(TEM)、X射线光电子能谱(XPS)和X射线衍射光谱(XRD)测试结果显示，非合金化的Pd-Au纳米粒子均匀分布在MWCNT表面。 循环伏安和计时电流测试显示，非合金化Pd-Au/MWCNT催化剂对甲酸氧化的电催化活性以及稳定性优于Pd/MWCNT催化剂。

| Abstract: | Naphthalen-1-ylmethylphosphonic acid was modified on multiwall carbon nanotube(MWCNT) by the π-π stacking interaction. Then, the Pd catalyst was supported on it. Furthermore, the MWCNT supported Pd-Au(Pd-Au/MWCNT) catalyst was facially prepared by the replacement reaction between Pd nanoparticles and HAuCl4. Transmission electron microscopy, X-ray diffraction and X-ray photoelectron spectroscopy measurements showed that non-alloyed Pd-Au nanoparticles were highly dispersed on the surface of MWCNT. Cyclic voltammetry and chronoamperometric measurements indicated that the Pd-Au/MWCNT catalyst exhibited better electrocatalytic activity and stability for formic acid oxidation than that of the Pd/MWCNT catalyst. |
