本文报道了一种新的多壁碳纳米管（MWCNT）负载的PtCo纳米催化剂的合成策略，该催化剂通过化学还原途径在深共晶溶剂（DESs）中合成。x射线衍射（XRD）和透射电子显微镜（TEM）结果表明，在MWCNTs表面沉积了约2.4 nm的合金PtCo纳米颗粒，聚集较少，团簇较大。x射线光电子能谱（XPS）测量揭示了PtCo/MWCNT催化剂中Pt和Co原子之间的强电荷转移相互作用。电化学测试表明，PtCo/MWCNT在甲醇氧化反应（MOR）中表现出比Pt/MWCNT更高的电催化活性、稳定性和CO耐受性。该研究表明，基于DESs的方法在设计和制造高效的dmfc电催化剂方面具有很大的潜力。
We herein report a novel strategy for multi-walled carbon nanotube (MWCNT)-supported PtCo nanocatalysts, which are synthesized in deep eutectic solvents (DESs) by a chemical reduction route. The X-ray diffraction (XRD) and transmission electron microscopy (TEM) results indicate that the alloyed PtCo nanoparticles of ca. 2.4 nm are deposited on the surface of MWCNTs with less aggregation in larger clusters. X-ray photoelectron spectroscopy (XPS) measurements reveal the strong charge transfer interaction between Pt and Co atoms in the PtCo/MWCNT catalyst. The electrochemical tests illustrate that the PtCo/MWCNT exhibits much higher electrocatalytic activity, stability and CO tolerance ability than the Pt/MWCNT catalyst for the methanol oxidation reaction (MOR). This study implies that the method based on DESs will be potential in design and fabrication of the highly efficient electrocatalysts for DMFCs applications.
