Fabrication of hierarchical porous metallic glasses decorated with Cu nanoparticles as integrated electrodes for high-performance non-enzymatic glucose sensing

A family of novel hierarchical porous metallic glasses decorated by Cu nanoparticles (PMGs & Cu-NPs) was synthesized through one-pot pulse anodization method on Zr65Cu22Al8Fe5 metallic-glass plates. The typical hierarchical porous morphology with two-levels pores in size of 9.74±2.4 μm and 1.41±0.41 μm was characterized for the samples pulse-anodized for 1800 s with a pulse period of 5 s etching and 10 s delay in 3.0 wt.% NaCl solution.
