Herein, multi-walled carbon nanotube (MWCNT) supported Zn–Pd and Zn–Pd–Pt catalysts have been prepared utilizing a sequential sodium borohydride (SBH) reduction method. The resulting Zn/MWCNT, Zn–Pd/MWCNT, and Zn–Pd–Pt/MWCNT catalysts were characterized using advanced surface analytical techniques such as X-ray diffraction (XRD), high contrast transmission electron microscopy (C-TEM), and X-ray photoelectron spectroscopy (XPS). The characterization results indicate that the Zn/MWCNT, Zn–Pd/MWCNT, and Zn–Pd–Pt/MWCNT catalysts were successfully prepared. It was observed that Pd and Pt incorporation into Zn alters the electronic structure of Zn. Cyclic voltammetry (CV), chronoamperometry (CA), and electrochemical impedance spectroscopy (EIS) were used to examine the electrochemical activity of the catalysts toward the electrooxidation of formic acid (FA). The results reveal that ZnPdPt/MWCNT has a specific activity of 12.6 mA/cm² and an electrochemical active surface area (ECSA) of 41.1 m²/g. This catalyst shows high activity, stability, and resistance when compared to Pd/MWCNT and ZnPd/MWCNT. Direct FA fuel cell (DFAFC) measurements were performed at 18–60 °C for the ZnPd/MWCNT and ZnPdPt/MWCNT catalysts. The specific activity of ZnPdPt/MWCNT was 1.45 times greater than that measured for ZnPd/MWCNT. ZnPdPt/MWCNT is a promising catalyst according to our CV, CA, EIS, and DFAFC measurements.

在此，采用连续硼氢化钠（SBH）还原法制备了多壁碳纳米管（MWCNT）负载的Zn-Pd和Zn-Pd-Pt催化剂。所得的Zn / MWCNT，Zn-Pd / MWCNT和Zn-Pd-Pt / MWCNT催化剂使用先进的表面分析技术进行了表征，例如X射线衍射（XRD），高对比度透射电子显微镜（C-TEM）和X射线光电子能谱（XPS）。表征结果表明，已成功制备了Zn / MWCNT，Zn-Pd / MWCNT和Zn-Pd-Pt / MWCNT催化剂。观察到，Pd和Pt结合到Zn中会改变Zn的电子结构。循环伏安法（CV），计时电流法（CA），电化学阻抗谱法（EIS）和电化学阻抗谱法（EIS）用于检查催化剂对甲酸（FA）的电氧化的电化学活性。结果表明ZnPdPt / MWCNT的比活度为12.6 mA / cm^在图2中，电化学活性表面积（ECSA）为41.1m ² / g。与Pd / MWCNT和ZnPd / MWCNT相比，该催化剂显示出高活性，稳定性和抗性。在18–60°C下对ZnPd / MWCNT和ZnPdPt / MWCNT催化剂进行直接FA燃料电池（DFAFC）测量。ZnPdPt / MWCNT的比活性是ZnPd / MWCNT的比活性的1.45倍。根据我们的CV，CA，EIS和DFAFC测量，ZnPdPt / MWCNT是一种有前途的催化剂。
