| 摘 要： | 为了获得钯镍合金纳米线条优秀的氢敏感性能,采用不同方法获得不同形貌的钯镍合金纳米线条阵列.用AAO模板可以制得连续光滑的纳米线条,在石墨阶梯边上沉积可以得到纳米粒子链,在铂微电极上交流电沉积能够得到多孔纳米线条和枝晶状纳米线条.氢传感实验表明,钯镍合金纳米粒子链和多孔纳米线条结构具有高的氢敏感性和快速响应能力,因此应使用这2种钯镍合金纳米结构材料制备氢传感器才能获得更好的性能.

| Abstract: | In order to optimize hydrogen-sensing performance of Pd-Ni alloy nanowire arrays,various Pd-Ni alloy patterns of nanowire arrays were made by various fabrication techniques.Continuous and smooth nanowires were fabricated in an anodic aluminum oxide(AAO) template.Nanoparticle chains of Pd-Ni alloy were produced at the step edges of highly oriented pyrolytic graphite.Dendrite or web porous nanowires were obtained on Pt microelectrodes by AC electrodeposition.Hydrogen-sensing experiments showed that nanopartic... |
