In semiconductor catalysts, rational doping of nonmetallic elements holds significant scientific and technological importance for enhancing photocatalytic performance. Here, using a one-step hydrothermal technique, we synthesized iodine-doped Bi3O4Cl composite evaluated the impact iodine on its capability organic dye degradation under visible light irradiation. this study, demonstrate that introduction iodide ions not only provides an ideal built-in electric field (BIEF) but also induces generation additional oxygen vacancies (OVs). The significantly enhanced BIEF, along with collaborative effect OVs-induced narrow bandgap in Bi3O4Cl, effectively promotes separation transfer efficiency photogenerated charges while suppressing recombination. Under driving force, electrons to surface OVs, facilitating activation oxygen, thereby forming highly active superoxide radicals (•O2). Simultaneously, vacancy engineering can reduce reaction energy barrier, formation singlet (1O2), which contributes processes. results indicate light, prepared exhibits 6.5-fold increase rate constant rhodamine B demonstrates activity toward methyl orange methylene blue. This study strong references optimizing structural design enhance performance offers profound insights into synergistic effects BIEF OVs charge mechanisms systems.
