摘要:
在聚乙烯吡咯烷酮(PVP)存在下,通过小的纳米粒子自组装,我们合成了具有纳米尺度直径和微尺度长度的纳米链.通过等离子体将该Ni纳米链处理,去除覆盖在其表面的PVP.得到的样品通过TEM、EDX、XRD等表征.本文并对Ni纳米链氧化乙硫醇的催化性能进行评价,结果表明,经过等离子体处理过的Ni纳米链的催化氧化乙硫醇性能优于其他的NiO催化剂.此外,我们也研究了催化剂的重复性效果.纳米粒子表面的性质在制备及应用过程中的重要性在此得到了验证,这些结果进一步表明纳米技术在催化领域具有潜在应用价值.
Abstract:
Ni nanochains with diameters of nanoscale and lengths of microscale were synthesized by the assembly of small nanoparticles in the presence of a multidentate ligand poly(vinyl pyrrolidone)(PVP).Then the Ni nanochains were treated by plasma to remove PVP that coated onto the surface of Ni nanochains.The samples were characterized by Transmission Electron Microscopy(TEM),Energy Dispersive X-ray Spectroscopy(EDX)and X-ray diffraction(XRD).The catalytic performance of Ni nanochains for the oxidation of ethanethiol was evaluated and the results showed that the catalyst activity of Ni nanochains is better than those of other NiO catalysts.The repeated catalytic activity of catalysts for the oxidation of ethanethiol was also investigated.The importance of the surface properties of nanoparticles in operating functionalities was recognized.These results suggest that nanotechnology developed here has the potential application in the field of catalysis.
