| 摘要: 以市售普通活性炭为碳源，先对其进行强碱活化处理制得多孔碳材料，再经硝酸氧化后，通过水热溶剂法将季鏻阳离子负载于多孔碳上，得到功能化的多孔碳材料。通过比表面积(BET)、热重分析 (TGA)、X射线衍射(XRD)、高分辨透射电镜(HRTEM)以及ζ电位对其形貌和结构进行分析，并对其抗菌活性进行表征。结果表明，该方法成功合成了功能化多孔碳材料，该碳材料在水溶液中具有较好的分散性、稳定性和荷电性，并对大肠杆菌(E. coli)和金黄色葡萄球菌(S. aureus)具有良好的抗菌活性。 |

| Abstract: To ordinary commercial activated carbon as carbon source, after activated by alkali, and then oxidized by nitric acid, a new porous carbon material mixed with quaternary phosphonium cations in different proportions via a simple solvothermal route was synthesized. Characterization of the morphology and structure were carried out by using Brunauer-Emmet-Teller (BET), thermogravimetric analysis (TGA), X-ray diffraction (XRD), high resolution transmission electron microscopy (HRTEM) and ζ potential analysis. And its antibacterial activity was characterized. The results show that the method successfully synthesized a functionalized porous carbon materials, the carbon composite material show good distribution stability and electrical charge, and perfect antibacterial activity to Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus). |
