“…Since the average Z number of the core (assumed to be Al 2 O 3 ) and the shell (assumed to be K-Si-O ceramics) are very close, the latter is not well pronounced. However, for some particles, especially in the case of the KAS40 sample, a sharp change in the contrast is observed, which can be attributed to core/shell structure [28][29][30][31] formation. The core and the shell are amorphous as can be seen from both electron diffraction patterns and TEM images (Fig.…”

The RF thermal plasma synthesis route was used for the preparation of alumo-silicate spherical particles. Homogeneous solid mixtures of raw materials (Al 2 O 3 , SiO 2 and KOH) were used as precursors. SiO 2 powders with different particle sizes (6 μm and 40 μm) were taken for this synthesis. For the characterization of obtained materials, scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray powder diffraction (XRD) analysis, infrared spectroscopy (FTIR) and thermogravimetric analysis (TG/DTA) were used. Nanosized amorphous ceramic particles were formed via two-step RF thermal plasma processing. It was demonstrated that the size of the SiO 2 particles plays a significant role in the formation of the alumo-silicate nanoparticles.

“…Hematite also functions as photocatalytic material since it is a semiconductor [ 17 – 21 ]. Fe 2 O 3 particles have been synthesized in various morphologies through hydrothermal [ 22 ], coprecipitation [ 23 ], solvothermal [ 24 ], spray pyrolysis [ 25 ] and sol-gel methods [ 26 ]. Photodegradation of various organics under UV light or daylight by synthesized Fe 2 O 3 particles has been researched in several studies.…”

In this study, an abundant and eco-friendly photocatalytic material, Fe 2 O 3 particles were synthesized by sonochemical method. Morphological and microstructural investigations of synthesized undoped and Ni, Co-doped Fe 2 O 3 particles were performed. The effect of particle morphology and microstructure on its photocatalytic performance was further investigated. Comparative studies for evaluating particle crystallite sizes were conducted by Williamson-Hall (W-H) method and modified Debye-Scherrer (MDS). Crystallite sizes and lattice strains of Fe 2 O 3 induced by process parameters were calculated by W-H method based on uniform deformation model (UDM). The crystallite sizes of the synthesized powders were calculated in the range of 200 nm and 76 nm by Williamson-Hall analysis. In addition to structural investigation, dislocation density of the synthesized particles was calculated by Williamson-Smallman relation. Afterwards, photocatalytic performance of Fe 2 O 3 particles was investigated in detail. The photodegradation of methylene blue solutions in the presence of light in 20 min with samples 3,4, and 5 in 20 min were 0.937, 0.896, and 0.855, respectively. Moreover, the photodegradation of methylene blue solution with sample 5 for 15, 30, and 45 min were 0.9, 0.828, and 0.757, respectively. A photocatalytic activity of 24.25% has been observed under optimum conditions for the time interval of 45 min.
