抗生素残留严重污染环境，引发诸多健康问题。在所有抗生素中，地表水和饮用水中的盐酸四环素（TC-HCl）引起了世界各国的广泛关注。采用一步水热法合成了具有中空微球的大规模SnO2，并将其作为高效光催化剂降解TC-HCl。采用XRD、SEM和EIS对合成的不同摩尔比的SnO2材料进行了晶体结构、形貌和电阻值的表征。在紫外光照射下，SnCl2·2H2O与Na3C6H5O7·2H2O的摩尔比为1:4合成的SnO2空心微球对TC-HCl的光催化降解活性最佳。新型SnO2空心微球具有独特的中空微观结构，具有良好的光催化性能，是合成C3N4-SnO2等光降解领域复合光催化剂的理想选择。
Antibiotic residues lead to serious environment pollution and provoke many health problems. Among all the antibiotics, Tetracycline hydrochloride (TC-HCl) in surface and drinking waters around the world has attracted widespread attention. Large-scale SnO2 with hollow microspheres were synthesized via one-step hydrothermal approach as a high-efficiency photocatalyst to degrade TC-HCl. These synthesized series of SnO2 materials with various molar ratios were characterized by XRD, SEM and EIS in terms of crystal structure, morphology, and electronic resistance. SnO2 hollow microspheres synthesized with SnCl2·2H2O to Na3C6H5O7·2H2O at the molar ratio of 1:4 showed the best photocatalytic degradation activity of TC-HCl under UV light illumination. The high photocatalytic property was considered to be benefit from the unique hollow microstructure, and the updated SnO2 hollow microspheres were good candidates for synthesis of composite photocatalysts in area of photo degradation, such as C3N4-SnO2, etc.
