Notes:
The current research aims to evaluate the photocatalytic activity of (TiO2) with various loading ratios (5%-60%) supported on mesoporous aluminosilicate (zeolite type) called Siral, with aluminum content ranging from 20% to 70%, to enhance the performance of degradation of ibuprofen (IBP) as a pharmaceutical pollutant. The batch reactor is furnished with solarium light to simulate sunlight UV for efficient degradation. The supported substance (Siral) exhibits elevated surface area and a regular mesoporous structure; hence, it might be regarded as an efficient photocatalyst support. The characterizations and effectiveness of the prepared catalyst were achieved by X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), scanning electron microscopy (SEM) and UV-visible spectroscopy. The results exhibit the highest photo-degradation ratio (90%) for (60% TiO2/Siral40) after 4 hours. The highest surface area is 448.3685 m²/g for 15% TiO₂/Siral40. The photodegradation efficiency increases as the weight percentage of TiO2 particles rises from 5 to 60 %. TiO2/Siral NCs photocatalysts demonstrate remarkable photostability and reusability, especially in organic molecule degradation.
