| Abstract: | Flower spherical Bi2S3/BiOI composite photocatalysts fabricated by nanosheets were synthesized by the hydrothermal anion transfer method from BiOI microspheres using thioacetamide as the sulfur source. The formaldehyde was used as the model pollutant to test the removal performance of the composite photocatalyst. The results showed that formaldehyde in air was removed under visible light. Bi2S3/BiOI composite photocatalyst with heterojunction structure had high photocatalytic activity and good cycling stability. |
