Highly porous materials have attracted intensive attention in the past decades due to their unique geometrical configuration, unusual structural features, and outstanding physicochemical properties, but the facile creation of porous metal nanomaterias remains a formidable challenge. Most reports focused on using hard templates to create porous metal nanomaterials via sacrificing the templates. Herein, we have created a new class of porous PtPb/Pt nanocrystals (NCs) with well-defined morphology, composition and porosity through a facile chemical etching approach. Due to the highly open three-dimensional (3D) structure and alloy effect, the porous PtPb/Pt NCs exhibit enhanced performances towards polyhydric alcohol electrooxidations with the optimized porous Pt3Pb nanoplates exhibiting superior activities of 1.75 mA cm−2 and 1.19 A mg−1Pt for ethylene glycol oxidation reaction (EGOR) and of 1.46 mA cm−2 and 1.00 A mg−1Pt for glycerol oxidation reaction (GOR) that are much higher than the commercial Pt/C (0.34 mA cm−2 and 0.22 A mg−1Pt for EGOR, 0.30 mA cm−2 and 0.20 A mg−1Pt for GOR). In addition, the porous Pt3Pb nanoplates can endure the long-term stability in EG and glycerol oxidation reactions with limited activity and structure change after 20,000 and 5,000 cycles, respectively, showing a highly promising class of porous Ptbased electrocatalysts for direct polyhydric alcohol fuel cells and beyond.

本论文采用简便的湿化学刻蚀法首次成功合成了具有明确形貌、 组分和多孔性的PtPb/Pt多孔纳米晶. 由于具有高度开放的三维立体结构和合金效应, PtPb/Pt多孔纳米晶的多元醇电催化性能良好. 其中, 最优化的Pt3Pb多孔纳米片在乙二醇氧化反应中的催化活性为1.75 mA cm−2和1.19 A mg−1Pt, 在丙三醇氧化反应中的催化活性为1.46 mA cm−2和1.00 A mg−1Pt, 均远远高于商业Pt/C催化剂的催化活性. 另外, Pt3Pb多孔纳米片在乙二醇和丙三醇氧化反应中均表现出优异的电催化稳定性, 分别经过20000个循环和5000个循环后, 其催化活性 没有发生明显衰减且纳米结构没有发生改变. 因此, Pt3Pb多孔纳米片可作为一种非常有发展前景的铂基电催化剂应用于多元醇燃料电池 及相关领域中.
