摘要
采用溶剂热法合成项链状的铂镍纳米线(PtNi NWs),将PtNi NWs封装UIO-67膜中,制得核壳结构催化剂PtNi@UIO-67。通过透射电镜(TEM)、比表面积及孔径分析仪(BET)、傅里叶红外光谱(FT-IR)、X射线粉末衍射(XRD)和电感耦合等离子体-原子发射光谱(ICP-AES)等研究手段对催化剂进行表征,并测试其在酸性环境下电催化析氢(HER)性能。结果表明:UIO-67膜的引入,对纳米线起到分散和保护作用,其催化活性和稳定性优于单独的PtNi纳米线。
The necklace-shaped PtNi nanowires(PtNi NWs)were synthesized by the solvothermal method,which were encapsulated in UIO-67membrane to produce the core-shell structure catalyst PtNi@UIO-67.The catalyst was characterized by transmission electron microscopy(TEM),specific surface area and pore size analyzer(BET),fourier transform infrared spectrometer(FT-IR),X-ray diffraction(XRD),and inductively coupled plasma-atomic emission spectroscopy(ICP-AES),and tested its electrocatalytic hydrogen evolution reaction(HER)performance under acidic environment.The results shown that the introduction of UIO-67membrane can disperse and protected the nanowire,and its catalytic activity and stability were better than that of PtNi NWs alone.
