Data from: Akaganeite nanorices deposited muscovite mica surfaces as sunlight active green photocatalyst

Thin-films of akaganeite [FeO(OH)] nanorices deposited muscovite mica
(ANPM) surfaces are produced using the facile urea assisted controlled
self-assembly technique. The synthesized materials are characterized using
scanning electron microscopy (SEM) with energy dispersive X-ray
spectroscopy (EDS), atomic force microscopy, X-ray diffraction (XRD),
Fourier transform infrared (FT-IR) spectroscopy and thermo gravimetric
analysis (TGA). The prepared nanorices on mica surfaces show average
particle length and width as 200 nm and 50 nm respectively. Synthesized
material acts as an efficient photocatalyst under UV and sunlight
conditions as demonstrated by the degradation of standard methylene blue
solution. The methylene blue degradation efficiencies of the catalyst
under exposure to 180 min sunlight and UV are 89% and 87.5% respectively
which shows that the catalyst is highly active under sunlight than under
UV light. Therefore, the synthesized material is a potential green
photocatalyst in efficient treatment of industrial dye effluents under
direct sunlight.

以简便的尿素辅助可控自组装技术，制备得到沉积于白云母（muscovite mica）表面的纤铁矿（akaganeite，[FeO(OH)]）纳米稻状薄膜（ANPM）。所合成的样品采用以下手段进行表征：搭载能量色散X射线能谱（EDS）的扫描电子显微镜（SEM）、原子力显微镜、X射线衍射（XRD）、傅里叶变换红外（FT-IR）光谱仪以及热重分析（TGA）。制备得到的云母表面纳米稻状颗粒的平均长度与宽度分别为200 nm与50 nm。所合成的材料在紫外光与日光条件下均展现出高效的光催化性能，该性能通过标准亚甲基蓝（methylene blue）溶液的降解实验得以验证：该催化剂在日光照射180分钟与紫外光照射180分钟下的亚甲基蓝降解率分别为89%与87.5%，表明其在日光下的催化活性优于紫外光条件。因此，该合成材料是一种具有应用潜力的绿色光催化剂，可用于直接日光照射下工业染料废水的高效处理。
