Abstract
In this study, Bi2WO6/BiOBr S-scheme heterojunction composites were synthesized via a one-step solvothermal method. The experimental results demonstrate that the Bi2WO6/BiOBr composites exhibit a significant redshift in the light absorption edge and a reduction in bandgap compared with that of individual Bi2WO6 and BiOBr. Meanwhile, the separation and transfer of photogenerated carriers were accelerated in Bi2WO6/BiOBr composites. In the photocatalytic degradation of tetracycline, the best composite displayed the highest photocatalytic activity, achieving a degradation efficiency of 91.3% after 60 min of light irradiation. Moreover, it maintained good stability even after four cycles. The enhancement in photocatalytic activity is primarily attributed to the formation of the S-scheme heterojunction and the strengthened interfacial interactions.
期刊介绍：
The Journal of the Chinese Chemical Society was founded by The Chemical Society Located in Taipei in 1954, and is the oldest general chemistry journal in Taiwan. It is strictly peer-reviewed and welcomes review articles, full papers, notes and communications written in English. The scope of the Journal of the Chinese Chemical Society covers all major areas of chemistry: organic chemistry, inorganic chemistry, analytical chemistry, biochemistry, physical chemistry, and materials science.
