Figure 9

(a) Formation of OH in the MB solution with FL solution (8 μL) without any photocalyst, and by the presence of neat CA mats (red dots), CA/CeNPs (orange dots), CA/CeNPs/Pt1 (blue dots), and CA/CeNPs/Pt5 (green dots). (b) Trapping experiment of active species during the MB photodegradation under visible irradiation (λ > 400 nm) of the CA/CeNPs, CA/CeNPsPt1, and CA/CeNPsPt5 mats (0.4 mg·mL−1). FA, ISO, and TQNare used to indicate formic acid, isopropyl alcohol, and thymoquinone quenchers, respectively.
