摘要: 采用氢气泡阴极沉积法成功制备了具有枝晶结构的三维分级多孔Au膜。本文详细研究了沉积电位、沉积时间、H2SO4浓度、前驱体浓度等沉积条件对形貌的影响。由枝晶构成的三维多孔金膜(3D PGFs)也可以通过方波电位法(SWP)制备。采用扫描电子显微镜(SEM)对泡沫膜的形貌进行了表征。研究表明,由纳米簇组成的3D PGFS对葡萄糖无酶传感具有良好的催化活性。 |

Abstract: Au films with three-dimensional (3D) hierarchical pores consisting of interconnected dendrite walls were successfully fabricated by a strategy of cathodic deposition utilizing the hydrogen bubble dynamic template. The deposition conditions like potential, deposition time, H2SO4 concentration, precursor concentrations were investigated in detail. Herein, 3D Au porous films (3D PGFs) with dendritic walls could also be prepared by square wave potential (SWP). The morphology of foam films were characterized by scanning electron microscopy (SEM). The 3D PGFs comprised of nanodendrites show good electrocatalytic activities in enzyme-free detection of glucose. |
