  Facile Surfactant-Free Synthesis of Composition-Tunable Bimetallic PtCu Alloy Nanosponges for Direct Methanol Fuel Cell Applications

  摘要：

  海绵状金属纳米材料因其独特的结构在储氢、过滤、传感器、异相催化和燃料电池等领域的广泛应用而备受关注。在这里，我们首次采用一种简便的、自下而上的方法，成功地制备出了由亚 4.5 纳米颗粒构建模块构成的成分可调的铂铜合金纳米海绵。由于多孔结构、结构缺陷以及铂和铜的协同效应，铂铜合金纳米海绵对甲醇氧化具有良好的电催化性能。与纯铂纳米海绵相比，PtCu2 合金纳米海绵的比/质量活性是纯铂纳米海绵的 5.84/2.93 倍。此外，PtCu 合金纳米海绵的稳定性和再活化能力也优于纯铂纳米海绵。

  Final reductions: Alloyed Pt–Cu nanodendrites are synthesized through a two‐step co‐reduction method, in which the reduction rate is controlled by the oxidative etchants and the reducing agents. These dendritic nanostructures are the result of overgrowth along the <111> axis of the face‐centered cubic structure and the coalescence of small dendritic seeds. These nanodendrites are highly active for

  最终还原：合金化的Pt-Cu纳米枝晶是通过两步共还原方法合成的，其中还原速率由氧化蚀刻剂和还原剂控制。这些树突状纳米结构是沿面心立方结构的<111>轴过度生长和小的树突状种子聚结的结果。这些纳米树枝状晶体因其独特的结构以及Pt和Cu的双功能性而对甲醇电氧化具有高活性。

  extensive efforts have been devoted to pursuing high‐performance nanocatalysts for fuel cells, both the high cost and sluggish reaction kinetics have been two major drawbacks that limited its commercial development. In this regard, we demonstrated a facile solvothermal method for the syntheses of an advanced class of PtCu nanocatalysts with a unique pentangle‐like shape. By combining the merits of a

  研究用于液体燃料氧化反应的活性和稳定电催化剂对燃料电池的大规模商业化具有重要意义。尽管人们已经为寻找用于燃料电池的高性能纳米催化剂付出了巨大的努力，但高成本和反应迟缓都是阻碍其商业发展的两个主要缺点。在这方面，我们展示了一种简便的溶剂热方法，用于合成具有独特五角形形状的高级PtCu纳米催化剂。通过结合高活性表面积的优点以及协同效应和电子效应，可以制备出类似五角形的Pt 3Cu纳米催化剂表现出优异的对乙二醇氧化的电催化活性，其质量和比活性分别为5162.6 mA mg -1和9.7 mA cm -2，分别比市售Pt / C高5.0倍和5.1倍。更重要的是，Pt 3 Cu五角形也表现出出色的长期稳定性，在500次循环后活性衰减较小，结构变化可忽略不计，这表明燃料电池及其他类型的阳极催化剂是另一类。

  Platinum alloy nanoparticles show great promise as electrocatalysts for the oxygen reduction reaction (ORR) in fuel cell cathodes. We report here on the use of N,N-dimethylformamide (DMF) as both solvent and reductant in the solvothermal synthesis of Pt alloy nanoparticles (NPs), with a particular focus on Pt-Ni alloys. Well-faceted alloy nanocrystals were generated with this method, including predominantly cubic and cuboctahedral nanocrystals of Pt3Ni, and octahedral and truncated octahedral nanocrystals of PtNi. X-ray diffraction (XRD) and high angle annular dark field scanning transmission electron microscopy (HAADF-STEM), coupled with energy dispersive spectroscopy (EDS), were used to characterize crystallite morphology and composition. ORR activities of the alloy nanoparticles were measured with a rotating disk electrode (RDE) technique. While some Pt3Ni alloy nanoparticle catalysts showed specific activities greater than 1000 mu A/cm(P nu)(2) alloy catalysts prepared with a nominal composition of PtNi displayed activities close to 3000 mu A/cm(P nu)(2) or almost 15 times that of a state-of-the-art Pt/carbon catalyst. XRD and EDS confirmed the presence of two NP compositions in this catalyst. HAADF-STEM examination of the PtNi nanoparticle catalyst after RDE testing revealed the development of hollows in a number of the nanoparticles due to nickel dissolution. Continued voltage cycling caused further nickel dissolution and void formation, but significant activity remained even after 20 000 cycles.
