Ultra-Rapid Synthesis of Co3O4 Nanostructures with Tunable Morphology via Nickel-Assisted Anodization Open
Various morphologies of cobalt oxide Co3O4 films on cobalt (Co) foils were obtained via anodization followed by a thermal treatment at 350 °C. This study introduces a rapid and cost-effective synthesis route, achieving well-defined spinel …
