  摘要：

  赋予电催化剂优势 铂（Pt）是燃料电池和电解槽中氧还原反应（ORR）的极佳催化剂，但由于价格昂贵且稀缺，即使以铂纳米颗粒的形式分散在碳电极载体（Pt/C）上，也无法广泛应用。另外、 陈 等人 (p. 1339 ，2 月 27 日在线发表；见以下作者的观点 Greer )通过溶解菱形十二面体铂镍 3 的内部，制成了高活性 ORR 催化剂。 3 纳米晶体的内部，留下富含铂的铂 3 Ni 边缘。这些纳米框架催化剂经久耐用--在 10,000 次电压循环后仍保持活性，而且活性远远高于 Pt/C。

  Pt3Ni alloy nanoparticle networks (Pt3Ni NN) were prepared through a simple one-step room-temperature synthetic method. The as-prepared Pt3Ni NN exhibited markedly improved activity for both oxygen reduction reaction and electrocatalytic oxidation of small organic molecules over the Pt nanoparticle networks (Pt NN) and commercially available Pt/C.

  通过简单的一步室温合成法制备了 Pt3Ni 合金纳米粒子网络（Pt3Ni NN）。与铂纳米粒子网络（Pt NN）和市售的 Pt/C 相比，制备的 Pt3Ni NN 在氧还原反应和小分子有机物电催化氧化方面的活性都有明显提高。
• Syntheses of Water-Soluble Octahedral, Truncated Octahedral, and Cubic Pt–Ni Nanocrystals and Their Structure–Activity Study in Model Hydrogenation Reactions

  We developed a facile strategy to synthesize a series of water-soluble Pt, PtxNi1-x (0 < x < 1), and Ni nanocrystals. The octahedral, truncated octahedral, and cubic shapes were uniformly controlled by varying crystal growth inhibition agents such as benzoic acid, aniline, and carbon monoxide. The compositions of the PtxNi1-x nanocrystals were effectively controlled by choice of ratios between the Pt and Ni precursors. In a preliminary study to probe their structure-activity dependence, we found that the shapes, compositions, and capping agents strongly influence the catalyst performances in three model heterogeneous hydrogenation reactions.
• A General Strategy for Preparation of Pt 3d-Transition Metal (Co, Fe, Ni) Nanocubes

  A facile, reliable, general, and robust synthetic method for preparation of high-quality, (100)-terminated Pt3M nanocubes (M = Pt or 3d-transition metals Co, Fe, and Ni) has been developed. It was identified that addition Of W(CO)(6) is crucial for control of the nucleation process when the metallic precursors are reduced, whereas an optimized ratio of the solvent pair, oleylamine and oleic acid, is the key to enabling the lowest total surface energy on 100} facets in order to develop cubic nanocrystals in the present system. The resultant monodisperse nanocubes, in which Pt is partially substituted, are expected to exhibit unusual electrocatalytic characteristics, providing an alternative for developing high-performance electrocatalysts for use in fuel cells.

  Carbon-supported Pt-based binary alloy electrocalalysts (Pt-Co, Pt-Cr and Pt-Ni) were prepared by incipient wetness method to investigate the origin of the enhanced activity of the oxygen reduction reaction in fuel cells. The composition of these catalysts was adjusted to 3:1 (Pt:M, atomic%, M = Co, Cr and Ni). Prepared catalysts were characterized by various physical and electrochemical techniques, that is, energy dispersive X-ray spectrometry (EDX), X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray absorption spectroscopy (XAS) and cyclic voltammetry (CV). XRD analysis showed that all prepared catalysts exhibited face-centered cubic structures and had smaller lattice parameters than Pt-alone catalyst. Pt-alone and Pt-based alloy catalysts showed increasing specific activities with decreasing surface area. This indicates that oxygen reduction on platinum surface is a structure-sensitive reaction. According to CV and X-ray absorption near-edge structure (XANES) results, the structure-sensitivity of Pt and Pt-based alloy catalysts for oxygen reduction seems associated with the adsorption strength of oxygen intermediates on the Pt surface. In addition, the Pt-based alloy catalysts showed significantly higher specific activities than Pt-alone catalysts with the same surface area. This phenomenon comes from the seduced Pt-Pt neighboring distance as the catalysts were alloyed. The reduced Pt-Pt neighboring distance is favorable for the adsorption of oxygen.

  This communication describes the preparation of carbon-supported truncated-octahedral Pt3Ni nanoparticle catalysts for the oxygen reduction reaction. Besides the composition, size, and shape controls, this work develops a new butylamine-based surface treatment approach for removing the long-alkane-chain capping agents used in the solution-phase synthesis. These Pt3Ni catalysts can have an area-specific activity as high as 850 mu A/cm(Pt)(2) at 0.9 V, which is similar to 4 times better than the commercial Pt/C catalyst (similar to 0.2 mA/cm(Pt)(2) at 0.9 V). The mass activity reached 0.53 A/mg(pt) at 0.9 V, which is close to a factor of 4 increase in mass activity, the threshold value that allows fuel-cell power trains to become cost-competitive with their internal-combustion counterparts. Our results also show that the mass activities of these carbon-supported Pt3Ni nanoparticle catalysts strongly depend on the (111) surface fraction, which validates the results of studies based on Pt3Ni extended-single-crystal surfaces, suggesting that further development of catalysts with still higher mass activities is highly plausible.
