“…Among these methods, photocatalysis is a powerful technique for environmental detoxification and has emerged as a promising solution due to its cost-effectiveness and environmental friendliness [12,13]. Various metal oxides, such as TiO 2 [14], ZnO [15], CuO [16], WO 3 [17], Fe 2 O 3 [18], and SrTiO 3 [19], are known for their ability to efficiently photocatalyze organic compounds and effectively inactivate bacteria via photocatalytic chemical reactions. Zinc oxide (ZnO), a group II-VI semiconductor material, is often considered one of the most promising photocatalytic agents due to its nontoxic nature and physical stability [20].…”

In the present study, different molar ratios of Fe-doped ZnO/biochar (FZBC) were synthesized using a coprecipitation method. ZnO nanoparticles with a size of approximately 30 nm were well dispersed on the biochar matrix. The bandgap energy decreases from 3.11 to 3.08 eV as the Fe-ion concentration increases from 1 to 7 mol%. Photocatalytic studies demonstrated that FZBC exhibited photodegradation toward acid orange 7 (AO7). FZBC exhibited a photodegradation efficiency of AO7 at a concentration of 10 mg. L-1 (93.17%), which was nine times greater than that of pure ZnO (10.30%). Furthermore, the FZBC materials also demonstrated effective inactivation of E. coli, with an antibacterial rate reaching 98%. Overall, these materials are expected to be cost-effective and suitable for photocatalytic degradation and antibacterial activities.
