摘要	We describe the one-step dealloying of PtNiAl ternary alloy to fabricate aligned nanoporous PtNi (np-PtNi) nanorod-like structures with predetermined alloy composition. Electron microscopy and X-ray diffraction characterizations demonstrate that the selective etching of Al from PtNiAl alloy with multiphases generates aligned np-PtNi alloy nanorods. The formation of nanoporous nanorod-like structures with uniform PtNi alloy ligament should be due to the fast diffusion, self assembly and strong interaction between Pt and Ni during the dealloying process. With the ligament size less than 5 nm, the np-PtNi nanorods exhibit remarkably improved electrocatalytic activity towards ethanol oxidation and H2O2 oxidation/reduction compared with the commercial Pt/C catalyst. When coupled with glucose oxidase, the enzyme modified np-PtNi electrode can sensitively detect glucose over a wide linear range (0.5-21 mM).
