We report flower-like morphology of iron oxide with nanosheets underneath it, on employing anodization technique at room temperature. FESEM was employed to verify the morphology. X-ray diffraction and Raman spectroscopy showed that all the fabricated nanostructures consist of magnetite and hematite phase. Moreover, the resulting Iron oxide nanoflowers were studied for light absorption using diffuse reflectance spectroscopy, showed the band gap of ∼2.09 eV. Photocurrent density of as-fabricated iron oxide nanoflowers were studied using electrochemical analyser and was found to be ∼0.35 mA cm⁻² which reveals their potential to be used as sunlight-driven photoelectrode material.

我们在室温下采用阳极氧化技术报告了其下方具有纳米片的氧化铁的花状形态。FESEM被用来验证形态。X射线衍射和拉曼光谱表明，所有制备的纳米结构均由磁铁矿和赤铁矿相组成。此外，使用漫反射光谱法研究了所得的氧化铁纳米花的光吸收，发现其带隙约为2.09 eV。使用电化学分析仪研究了制成的氧化铁纳米花的光电流密度，发现其约为0.35 mA cm ^-2，这表明它们有潜力用作阳光驱动的光电极材料。
