Abstract
4 Summery and Conclusion
Water is an important source for the survival of life and as a result of the pollution that the water witnessed recently, it was necessary to find an effective way to treat it after the traditional methods failed to achieve this goal, so our goal was to find a method that does not produce secondary pollutants. This method is Electrospinning Technique.
The study is divided into three chapters:
4.1 Chapter One:
This chapter represents the introduction to the present work which includes a general background of the preparation of TiO2, MoS2 and WS2 by electrospinning technique. Also, some of research reviews published in advance in this field was listed in this chapter.
4.2 Chapter Two:
This chapter includes the different experimental techniques that have been used for investigation the morphology, optical and scanning electron microscope (SEM), X-ray diffraction (XRD), FT-IR spectra, Raman spectroscopy, and UV-diffuse reflectance (UV-DRS).
4.3 Chapter Three:
In this chapter, the experimental results obtained from the structural, thermal, optical and electrical measurements of WS2/TiO2 nanofibers and MoS2/TiO2 nanofibers. we have successfully prepared WS2/TiO2 nanofibers with different ratios between WS2 (1D) and TiO2 (2D), respectively. Structural and morphological analyses of the prepared nanofibers confirmed the incorporation between WS2 and TiO2. Significantly, the photocatalytic efficiency of TW40 for phenol degradation was as high as 83%. The remarkable photocatalytic performance of TW40 (1D/2D structure) was attributed to the synergism effect between WS2 and TiO2 to improve electron transfer. In addition, the linkage between WS2 and TiO2 enhanced the photocatalytic stability of the nanofibers. The trapping test for the photogenerated free radicals and holes of TW40 demonstrated that the hydroxyl radicals photogenerated (•OH) has a significant role in the photo-degradation of phenol as an organic pollutant. Therefore, WS2/TiO2 nanofibers act as promising materials for photo-degradation of organic pollutants in water. we have successfully prepared MoS2/TiO2 nanofibers with different ratios between MoS2 and TiO2 (1D and 2D), respectively. Structural and morphological analyses of the prepared nanofibers confirmed the incorporation between MoS2 and TiO2. Significantly, the photocatalytic efficiency of TM40 for phenol degradation was as high as 96%. The remarkable photocatalytic performance of TM40 (1D/2D structure) was attributed to the small amount of (1T) MoS2 acting as a cocatalyst between 2H MoS2 and TiO2 to improve electron transfer. In addition, the synergistic effect between MoS2 and TiO2 enhanced the photocatalytic stability of the nanofibers. The trapping test for the photogenerated free radicals and holes of TM40 demonstrated that the hydroxyl radicals photogenerated (•OH) has a significant role in the photo-degradation of phenol as an organic pollutant. Therefore, MoS2/TiO2 nanofibers act as promising materials for photo-degradation of organic pollutants in water.
