Reasonable design and development of catalysts with specific components and morphologies can effectively improve the catalytic performance of nanomaterials. Here, we propose a controllable strategy to prepare atomically thin defect-rich Pd@PdOs nanobelts (Pd@PdOs NBs) with a thickness of 1.8 nm for ethylene glycol oxidation reaction (EGOR). Due to the abundant structural defects and extended active sites, Pd@PdOs NBs show excellent activity and stability in the EGOR. The mass activity and specific activity of Pd@PdOs NBs are 1.45 A mg⁻¹ and 1.78 mA cm⁻², marking a remarkable 3.1 times and 1.8 times increase compared to those of commercial Pd black catalysts. This breakthrough paves the way for the deliberate design and fabrication of defect-rich, atomically thin metal nanobelts for highly efficient electrocatalytic applications.

富缺陷的Pd@PdOs纳米带用于乙二醇电催化氧化

合理设计和开发特定组分和形貌的催化剂可以有效提高纳米材料的催化性能。在这里，我们提出了一种可控策略来制备厚度为1.8 nm的原子薄的富含缺陷的Pd@PdOs纳米带（Pd@PdOs NBs），用于乙二醇氧化反应（EGOR）。由于丰富的结构缺陷和扩展的活性位点，Pd@PdOs NBs在EGOR中表现出优异的活性和稳定性。 Pd@PdOs NBs的质量活性和比活性分别为1.45 A mg ^-1和1.78 mA cm ^-2，与商用钯黑催化剂相比分别提高了3.1倍和1.8倍。这一突破为高效电催化应用的富缺陷、原子级薄金属纳米带的精心设计和制造铺平了道路。
