Effective degradation of acid orange 7 on silver chloride/bismuth iodide (Bi3+: 4) hybrid nanophotocatalyst under simulated sunlight

By the development of industries, the amount of organic pollutants has also increased in the environment significantly. Dye contaminants which are more resistant are one of them1, 2. To tackle this issue, various forms of techniques are applied, but the photocatalytic approach has attracted a lot of attention as one of the most environmentally friendly method2, 3. Herein, degradation of acid orange 7 (AO7) with 100 mg/L concentration was studied during 180 min under simulated sunlight over plasmonic AgCl, silver chloride/bismuth iodide (Bi3+:4) (25:75) (denoted as: plasmonic AgCl-BOI (25:75)) and bare bismuth iodide(Bi3+:4) nanophotocatalysts that the photocatalytic degradation was obtained 43.2, 90.1 and 45.5%, respectively. Fig. 1 displays the absorption spectra of AO7 over plasmonic AgCl-BOI (25:75) at different irradiation time. Moreover, XRD, FESEM, and DRS analysis are used to demonstrate the true synthesis of nanophotocatalysts and the discussion of results gained.
