Abstract
This study highlights the highly efficient adsorption, photocatalytic properties, and stability of synthesized titanium dioxide (TiO2) photocatalyst incorporated into Chitosan (Cs) and supported onto the glass as substrate toward photodegradation of methyl orange (MO) pollutants. TiO2 was produced using a sol-gel technique, then ex situ synthesized with Cs solution and immobilized on a glass substrate at various weight ratios. The percentages and concentrations of the sorption in dark ambient are calculated in addition to photodegradation of MO under UV light irradiation. At acidic conditions, the photocatalyst with a 2:2 weight ratio of Cs-TiO2 had the optimum dye removal activity (91%). As a result, the work adds to the knowledge of adsorption and photodegradation in the green mitigation of persistent pollutants.
