In the present letter, we report a simple method for fabricating self-ordered CoFe₂O₄ nanoporous oxide layers by electrochemical anodization. For that, optimal electrolyte and anodization conditions were applied for anodizing the parent alloy FeCoV sheet, leading to an ordered nanoporous structure of CoFe₂O₄. The as-synthesized sample are characterized by Scanning Electron Microscopy (SEM), X-ray spectroscopy (EDS) and X-ray Diffraction (XRD). Our SEM findings showed nanopores size constant in the range of 15 nm independent of anodization potential. Also, our XRD measurements, along with the energy dispersive measurements confirm the transformation of the as-anodized nanoporous oxide layers into nanoporous oxide layers CoFe₂O₄ phase.

在本信中，我们报告了一种通过电化学阳极氧化制备自定序的CoFe ₂ O ₄纳米多孔氧化物层的简单方法。为此，采用了最佳的电解质和阳极氧化条件来对母体合金FeCoV片进行阳极氧化，从而形成有序的CoFe ₂ O ₄纳米孔结构。合成后的样品通过扫描电子显微镜（SEM），X射线光谱（EDS）和X射线衍射（XRD）进行表征。我们的SEM结果表明，纳米孔的尺寸常数在15 nm范围内，与阳极氧化电势无关。此外，我们的XRD测量以及能量色散测量结果证实了阳极氧化后的纳米多孔氧化物层已转变为纳米多孔氧化物层CoFe。₂ O ₄相。
