Abstract

This work presents the synthesis and characterization of a novel bentonite/TiO₂QDs (BNT/TD) nanocomposite specifically designed for the degradation of Brilliant blue R dye, a ubiquitous industrial contaminant. BNT/TD nanocomposite was meticulously crafted via a Co-precipitation method. This technique ensured the uniform distribution of nano TiO₂ onto the BNT surface. BNT/TD nanocomposite exhibited a significantly enhanced surface area (233.85 m²/g) compared to BNT. Moreover, the nanocomposite possessed a distinguishable bandgap of 3.18 eV as a crucial prerequisite for photodegradation processes. The photodegradation processes of Brilliant blue R dye in presence of BNT/TD was evaluated under different irradiation sources and their remarkable photocatalytic activity, achieving a degradation rate of 17.77 × 10^-3 s⁻¹, significantly near relative to TD (20.50 × 10^-3 s⁻¹). Furthermore, the reusability of BNT/TD was assessed through eight photocatalytic cycles. Also, the financial photodegradation process cost for 1000 m³ of Brilliant blue R dye was calculated.
