Formation of spinel CoFe2O4 nanoporous oxide layers by electrochemical anodization

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.

Automated summary

A simple method for fabricating self-ordered CoFe2O4 nanoporous oxide layers by electrochemical anodization is reported in this letter. Optimal electrolyte and anodization conditions were used to achieve an ordered nanoporous structure of CoFe2O4. Characterization by SEM, EDS, and XRD confirmed the nanopores size remained constant at 15 nm regardless of anodization potential, and the transformation of the as-anodized nanoporous oxide layers into CoFe2O4 phase was confirmed.
