Herein, Pd and a series of PdZn bimetallic nanoparticles supported on Vulcan XC-72 carbon were prepared by ultrasound-assisted NaBH₄ impregnation-reduction method for the oxidation reaction of BH₄⁻ (BOR). The physical properties of the electrocatalysts were identified by X-ray diffraction, X-ray photoelectron spectroscopy, transmission electron microscopy and inductively coupled plasma optical emission spectrometry techniques. The electrochemical properties were characterized by cyclic voltammetry, chronoamperometry and linear sweep voltammetry (LSV). The results were indicated uniformly dispersed PdZn nanoparticles on carbon with an average particle size of 5 nm. The number of electrons calculated from LSV data was found to be in the range of 3.0–3.5. Among all the prepared catalysts, PdZn-01/C exhibited the highest current density (1818 mA mg_Pd⁻¹) and stability towards BOR.

在本文中，通过超声辅助 NaBH ₄浸渍还原法制备了 Pd 和一系列负载在 Vulcan XC-72 碳上的 PdZn 双金属纳米粒子，用于 BH ₄ ^-的氧化反应。(BOR)。通过X射线衍射、X射线光电子能谱、透射电子显微镜和电感耦合等离子体发射光谱技术对电催化剂的物理性质进行了鉴定。通过循环伏安法、计时电流法和线性扫描伏安法（LSV）表征电化学性质。结果表明 PdZn 纳米颗粒均匀分散在碳上，平均粒径为 5 nm。发现从 LSV 数据计算的电子数在 3.0-3.5 的范围内。在所有制备的催化剂中，PdZn-01/C 表现出最高的电流密度（1818 mA mg _Pd ^-1）和对 BOR 的稳定性。
