花球状Bi2S3/BiOI复合光催化剂去除空气中甲醛的应用
Application in Removal of Formaldehyde in Air by Flower Spherical Bi2S3/BiOI Composite Photocatalyst
【摘要】 以硫代乙酰胺为硫源,采用水热阴离子转移法,制备由纳米片组装的花球状Bi2S3/BiOI复合光催化剂。以气相甲醛作为模型污染物,在检测舱中考察了复合催化剂对甲醛的去除作用。结果表明,具有异质结结构的Bi2S3/BiOI复合光催化剂具有较高的光催化活性,能在可见光下去除空气中的甲醛,并且具有良好的循环使用稳定性。
【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.
