Adjusting the morphology and composition of Pd-based materials is a promising strategy to improve their performance for the electrocatalytic formic acid oxidation reaction (FAOR). In this work, we report the preparation of B-doped PdRu nanopillar assemblies (B-PdRu NPAs) by a two-step method using NaBH₄ as the boron dopant. On combining the hyper-branched structure and the multi-component synergistic effect, B-PdRu NPAs achieve a high mass activity of 1.09 mA μg⁻¹_Pd for the FAOR and retain 73.19% of the initial activity after 500 cycles, which is superior to undoped counterparts. The proposed synthesis strategy provides a simple method for the synthesis of metal–nonmetal nanomaterials with desired composition and design structure for electrocatalytic fields.

B掺杂的PdRu纳米柱组件，用于增强甲酸氧化电催化。

调整Pd基材料的形貌和组成是提高其电催化甲酸氧化反应（FAOR）性能的一种有前途的策略。在这项工作中，我们报告了使用NaBH ₄作为硼掺杂剂的两步法制备B掺杂PdRu纳米柱组件（B-PdRu NPA）。通过结合超支化结构和多组分协同效应，B-PdRu NPA对FAOR的质量活度为1.09 mAμg- ¹ _Pd，在500次循环后保留了初始活度的73.19％，优于未掺杂的同行。提出的合成策略为合成具有电催化领域所需组成和设计结构的金属-非金属纳米材料提供了一种简单的方法。
