摘要
为了获得高负载、单分散的Pt/DCNTs异质结构,提出一种单步微波加热多元醇的方法.分别利用透射电子显微镜(TEM)和X射线衍射仪(XRD)表征了Pt/DCNT异质结构的形貌及成分.同时样品的拉曼光谱和傅里叶变换红外光谱(FTIR)表明:在微波处理下的双壁碳纳米管表面上有大量的缺陷或功能团产生,而它们的产生是Pt纳米粒子沿着双壁碳纳米管骨架成核与生长的关键因素.
High-density attachment and array monodispersive Pt nanoparticles （NPs） on double-walled carbon nanotubes （DCNTs） to generate Pt/DCNTs hybrids are obtained via one-pot microwave polyol method. The morphology, composition of as-obtained Pt/DCNTs hybrids are characterized by transmission electron microscopy （TEM）, X-ray diffraction （XRD）. The Raman spectrum and Fourier transform infrared （FTIR） spectrum show the introduction of defects or functional groups on DCNTs surface, which are crucial factors to assist the nucleation and growth of Pt NPs along the skeleton of DCNTs.
