Flower-shaped magnetically recyclable ZnS/ ZnIn2S4/Fe2O3 nanocomposites towards decolorization of colored pollutants

چکیده مقاله

Innovation the photocatalysts with acceptable performance, and facile recycle ability with magnetic separation is one of the most important challenges for researchers because of they are the promising materials can help to environmental health. Fe2O3 nanostructures with different ration loaded on ZnS/ZnIn2S4 nanocomposite were efficaciously provided through glycothermal procedure. The effect of amount of Fe2O3 nanostructures on structural, physical, magnetic and photocatalytic attributes of the resultant nanocomposite was explored. Morphology, uniformity and size of magnetic recyclable photocatalysts were detected, and present a flower shaped microstructures with assembling the nanosheets. Based on magnetic hysteresis, ternary ZnS/ZnIn2S4/Fe2O3 nanocomposite exposed the maximum saturation magnetization of 0.5481 emu/g which is higher than binary ZnS/ ZnIn2S4 nanocomposite. Photocatalytic decolorization of ZnS/ZnIn2S4/Fe2O3 nanocomposites was conducted in Rhodamine B (RhB) and Methyl orange (MO) solutions illuminated under a 400 W Osram lamp. The outcomes discovered that 95.07% and 56.42% of RhB and MO was removed for the ZnS/ZnIn2S4/Fe2O3 nanocomposites with ratio of 1:1 from Fe2O3:Zn. Moreover, it can be simply separated and recycled after being used five times and the degradation efficiency remains 60.83%. Compared to the other catalysts, the magnetic ZnS/ZnIn2S4/Fe2O3 nanocomposites is suitable for large scale requests in industrial water treatment system.
