TiO/SbS/GQDs nanocomposite was prepared by solvothermal method to study its antibacterial properties. XRD, SEM, EDX, FT-IR and TEM were used to characterize prepared nanomaterials. To evaluate effect of graphene quantum dots (GQD) on the antibacterial activity of final products, antibacterial activity of TiO, TiO/GQDs, SbS, SbS/GQDs were compared with TiO/SbS/GQDs. TiO/SbS/GQDs shows the highest antibacterial activity against E. coli and Staphylococcus aureus. TiO/SbS/GQDs show the lowest measure the minimal inhibitory concentration against E. coli and Staphylococcus aureus. MIC for E. coli and Staphylococcus aureus are 0.03 and 0.1, respectively.
采用溶剂热法制备了 TiO/SbS/GQDs 纳米复合材料，研究其抗菌性能。采用 XRD、SEM、EDX、FT-IR 和 TEM 对制备的纳米材料进行了表征。为了评估石墨烯量子点 (GQD) 对最终产物抗菌活性的影响，比较了 TiO、TiO/GQDs、SbS、SbS/GQDs 与 TiO/SbS/GQDs 的抗菌活性。TiO/SbS/GQDs 对大肠杆菌和金黄色葡萄球菌表现出最高的抗菌活性。TiO/SbS/GQDs 对大肠杆菌和金黄色葡萄球菌的最低抑菌浓度最低。对大肠杆菌和金黄色葡萄球菌的 MIC 分别为 0.03 和 0.1。
