“…The diffraction peaks for pure α-Fe 2 O 3 film were noticed at 2θ 113), (024), ( 116), ( 214), (300) crystal planes, which are consistent with what was mentioned in the foregoing works. 1,4 The same diffraction peaks were appeared for each Cu-doped iron oxide films (CF-2%, CF-4%, CF-6% and CF-8%), as shown in Figure 1B-E. As indicated in the Table 1, the diffraction peaks of all sprayed films are slightly shifted in their positions compared to the standards of hematite α-Fe 2 O 3 structure (JCPDS 33−0664 in Figure 1).…”

“…[29][30][31][32][33] The 3-D analysis, as per our literature review, on how the Cu doping affected to the based microtexture of α-Fe 2 O 3 nanomaterial is not reported. In this fresh work we report on the structural and optical properties of the pure α-Fe 2 O 3 and different wt% (2,4,6,8) of Cu-doped α-Fe 2 O 3 (CF-2%, CF-4%, CF-6% and CF-8%) thin films prepared by air pneumatic spray technique. Furthermore, we have studied the effect of Cu doping on the surface microtexture of the sprayed α-Fe 2 O 3 thin films via a stereometric and fractal analysis using AFM image data and statistical parameters, in accordance with ISO 25178-2: 2012.…”

The stereometric and fractal concepts are crucial tools to analyse, to verify, to report 3‐D microtexture of thin film surfaces on the nanometre scale and thereby to generate useful topographic characteristics for better understanding and steering them toward further improvements and rational use in modern applications. At first, the present work aimed to prepare hematite α‐Fe2O3 thin films with (0, 2, 4, 6 and 8 wt%) of Cu doping by using the air pneumatic spray method. Subsequently, the obtained pure α‐Fe2O3 and Cu‐doped α‐Fe2O3 thin films were characterised by XRD device, which determines their polycrystalline nature with the rhombohedral hematite structure. Analysis by UV‐VIS absorption showed that the transmittance of the thin films is extinct in the wavelength from approximately 500 to 800 nm, revealing that the films have good optical absorbance in the visible region. The obtained bandgap values varied between 2.23 and 2.21 eV. At second stage, the stereometric and fractal analysis are applied on 3‐D image data of pure α‐ Fe2O3 and Cu‐doped α‐Fe2O3 thin films, which in prior generated using AFM device. Accordingly, the obtained statistical parameters such as surface roughness, density distribution of peaks, depths etc. were used to understand the influence of Cu doping on the 3D microtexture of pure α‐ Fe2O3 and Cu‐doped α‐ Fe2O3 thin film surfaces.

The rapid urbanization and industrialization is causing worldwide water pollution, calling for advanced cleaning methods. For instance, pollutant adsorption on magnetic oxides is efficient and very practical due to the easy separation from solutions by an magnetic field. Here we review the synthesis and performance of magnetic oxides such as iron oxides, spinel ferrites, and perovskite oxides for water remediation. We present structural, optical, and magnetic properties. Magnetic oxides are also promising photocatalysts for the degradation of organic pollutants. Antimicrobial activities and adsorption of heavy metals and radionucleides are also discussed.

The present study uses Adenanthera pavonina L. plant extract to synthesize Y/Fe2O3 nanoparticles in a sustainable and efficient manner. Several physicochemical investigations were performed on the synthesized Y/Fe2O3 to evaluate its structure and morphological characteristics. The high crystallinity of Fe2O3 and decreased crystal size of Y/Fe2O3 were revealed by the XRD study. The formulated Y/Fe2O3 was spherical in shape. Y/Fe2O3 has shown potential photocatalytic activity in the degradation of congo red and brilliant green dyes in the presence of visible light. Degradation efficiency is higher than 90% for both dyes. In addition, the antibacterial activity of Y/Fe2O3 was measured against pathogenic strains of Bacillus subtilis, Escherichia coli, Klebsiella pneumoniae, Micrococcus luteus, Proteus mirabilis, Pseudomonas putida, Shigella dysenteriae, and Staphylococcus aureus. Y/Fe2O3 showed promising antibacterial activity against all microorganisms. Micrococcus luteus showed a higher zone of inhibition (equal to 35 mm in diameter) than other microorganisms using Y/Fe2O3. Thus, it is established that the green synthesized Y/Fe2O3 nanoparticles are active catalysts for the photocatalytic degradation of hazardous dyes and have antibacterial properties against different bacterial stains.
