摘要

通过水溶胶凝胶法获得了含有 B2O3 和 Nb2O5 的二氧化钛粉末。制备的凝胶在 200°C - 500°C 的温度范围内分步加热，随后通过 XRD、IR 和 UV-Vis 分析进行表征。TiO2（锐钛型）是单晶相，其检测温度高达 500°C。光催化测试表明，所研究的样品对孔雀石绿有机染料具有光催化活性，TiO2/Nb2O5 的光催化活性高于 TiO2/B2O3 样品。这些组合物对大肠杆菌 NBIMCC K12 407 和枯草杆菌 NBIMCC 3562 具有良好的抗菌活性。

INFLUENCE OF Nb2O5 AND B2O3 ON THE PHOTOCATALYTIC AND ANTIBACTERIAL ACTIVITY OF SOL-GEL DERIVED TiO2 NANOPОWDERS

TiO2 based powders containing B2O3 and Nb2O5 were obtained through an aqueous sol-gel method. The as prepared gels were step wisely heated in the temperature range 200°C - 500°C and subsequently characterized by XRD, IR and UV-Vis analysis. The TiO2 (anatase) is the single crystalline phase which has been detected up to 500°C. Photocatalytic tests showed that the investigated samples possess photocatalytic activity toward Malachite green organic dye and TiO2/Nb2O5 exhibited higher photocatalytic activity than TiO2/B2O3 sample. The compositions exhibited good antimicrobial activity against E. coli NBIMCC K12 407 and Bacillus subtilis NBIMCC 3562.
