Abstract
Nanotechnology from titanium dioxide has been deposited, and its application in desalination and water treatment has been investigated by using sol-gel methods. Homogeneously dispersed sphere shapes of titanium dioxide nanoparticles were observed from scanning electron microscope micrographs and decrease in size as aging time increases from 40 min to 60 min. SEM micrographs of highly transparent nanopowders show that they are detected in the visible region from UV/visible and that their red shift around maximum wavelength increases with increasing aging time due to an increase in water quality. The energy band gap of the generated nanosheet has narrowed as the aging time has increased, which is related to the red shift of the absorption spectrum edge in the sheet. The structural behaviors of deposited nanoparticles have also been investigated, which confirms the existence of anatase as well as rutile levels in the liquid phase. The findings of the PL allowed us to determine the total strength of the intensity. This shows that applying photodegradation by a solar absorber could play a vital role in desalination and water treatment.
Highlights
The important thing for human life is clean water which is a critical feedstock in a variety of key productions including electronics, pharmaceuticals, and nutrition [1]
Our nanosheet could recuperate the fluidity upon visible light treatment
We qualified this to the photodegradation of the collected wastewater when applied visible light treatment
Summary
The important thing for human life is clean water which is a critical feedstock in a variety of key productions including electronics, pharmaceuticals, and nutrition [1]. The objective of the current study was to synthesize and characterize TiO2 nanoparticle sheets as solar absorber and study its application in wastewater treatment and desalination, deposited under different aging times at 40 min, 50 min, and 60 min. It is employed in the synthesis of tints, fabrics, sheets, polymers, cosmetic, and foodstuffs, as well as in the production of dyes. Sol- (solution-) gel (molten) systems are from the most encouraging and effective methods used in nanoparticle fabrication This technique yields high crystal oxides by permitting regulator in nanoparticles size and surface morphology as well as phase configuration in different concentration precursors, and it is easy to operate. The present study is aimed at desalinating and treating water by using TiO2 nanoparticle sheets as solar absorber with varying aging times at 40 min, 50 min, and 60 min
