This study presents a facile one-pot synthesis method to fabricate BiFeO3-Bi25FeO40-Bi2O3 heterojunction photocatalysts with controllable compositions and pure phases. Three different binary heterojunctions (BiFeO3/Bi25FeO40, BiFeO3/Bi2O3, Bi25FeO40/Bi2O3) ternary BiFeO3/Bi25FeO40/Bi2O3 were formed, all exhibiting significantly enhanced photocatalytic performance for the degradation of methylene blue (MB) phenol under visible light irradiation, outperforming individual compositions. Notably, BiFeO3/Bi25FeO40 achieved highest efficiency (93.68% 83.3% MB phenol, respectively) as well excellent stability. Impressively, was even over twice that BiFeO3 Bi25FeO40, four times higher than Bi2O3. The activity is primarily attributed advantageous S-scheme band alignments facilitate efficient charge separation enhance redox capabilities. While other also exhibited improved efficiency, each unique combination materials led distinct electronic structures diverse reaction mechanisms. simplicity scalability method, combined remarkable these materials, position them highly promising candidates applications in environmental remediation solar energy conversion.
