“…Preparation of catalyst: Synthesis of mixed metal oxides SnO 2 -MgO nanoparticles was previously performed by sol gel method as reported by Bayal and Jeevanandam [24] in which to a solution of salts of both metals (tin chloride and magnesium methoxide) the ammonium hydroxide is added drop-wise. The formed metal hydroxides are separated and calcinated at high temperatures.…”

“…When MgO is introduced in SnO 2 it nucleates as a second phase and migrates to the surface of SnO 2 . MgO covers SnO 2 and suppresses the crystal growth of SnO 2 leading to the reduction of the crystallite size of SnO 2 [24].…”

The olive oil industry in Palestine is an important and widely spread one and accomplished with the release of large amounts of olive-mills wastewater. This wastewater represents a significant environmental problem due to its high phenolic content. In this work, the photocatalytic degradation of the some phenolic compounds (gallic acid, oleuropein and resorcinol) present in olive-mills wastewater using the synthesized nanoparticles of mixed SnO2-MgO catalyst and solar irradiation was performed. The nanoparticles of mixed SnO2-MgO catalyst with different ratios were prepared by sol gel method using a modified procedure. The obtained particles were characterized by SEM and XRD. The particle size was determined as 4.32 ± 0.42 nm which is much smaller than those previously prepared by standard procedures. The degradation percentage of phenolic compounds was measured by UV spectrophotometry. The effect of time, catalyst amount and phenolic compound concentration on degradation efficiency was studied. The maximum degradation was achieved using SnO2-MgO (4:1) catalyst, 2.5 mg catalyst per 5 mL solution, within the time of 60-120 min and ranged from 51 to 90 % for different concentrations of phenolic compounds.Keywords: Photocatalytic degradation, Olive mill wastewater, Gallic acid, Resorcinol, Oleuropein.Asian Journal of Chemistry; Vol. 30, No. 9 (2018), 1994-1998 This is an open access journal, and articles are distributed under the terms of the Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0) License, which allows others to copy and redistribute the material in any medium or format, remix, transform, and build upon the material, as long as appropriate credit is given and the new creations are licensed under the identical terms.

Abstract.We have reported the role of annealing temperature Fe 3 O 4 /SnO 2 nanocomposites as a photocatalyst for remove methylene blue (MB) dye from aqueous solution. However, how to enhanced the degradation performance of Fe 3 O 4 /SnO 2 nanocomposites is important to its photocatalytic application. Therefore, in this work Fe 3 O 4 /SnO 2 nanocomposites was combined with two different types of graphene materials (NGP and grahene) to improve the photocatalytic performance for remove methylene blue (MB) dye. Fe 3 O 4 /SnO 2 /NGP and Fe 3 O 4 /SnO 2 /graphene have been successfully synthesized by co-precipitation method. The influence of two types graphene on Fe 3 O 4 /SnO 2 nanocomposites properties were systematically investigated by means of X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy and Thermal gravimetric analysis (TGA). Degradation of methylene Blue (MB) in aqueous solution was studied in detail under photocatalytic process. Effect of catalyst dosage (0.1-0.4 g/L) and scavengers on dye degradation were carried out to check the efficiency of photocatalyst. The results indicated Fe 3 O 4 /SnO 2 /graphene displayed higher photocatalytic activity than other catalyst. The reusability tests have also been done to ensure the stability of the used photocatalyst.
