【摘要】 以硝酸镁、乙二胺四乙酸、三乙醇胺、柠檬酸等为原料,采用溶胶凝胶法制备了掺杂介孔氧化镁。通过XRD、BET、TEM等分析测试手段,系统研究了煅烧温度、煅烧时间、表面活性剂用量对氧化镁形貌以及比表面积的影响。获得孔径分布在3.6⁹.8nm,比表面积分布在80¹81.6m2/g的介孔氧化镁。考察了Li⁺、Cu²⁺、Al³⁺、Ti⁴⁺4种离子掺杂对氧化镁比表面积以及抗菌性能的影响。更多还原

【Abstract】 Mesoporous magnesium oxide with doping ion was prepared by a sol-gel method using magnesium nitrate, EDTA, triethanolamine and citric acid as the raw materials. By XRD, BET, and TEM, the effects of calcination temperature, calcination time and surfactant usage on the morphology and specific surface area of magnesium oxide were explored. Mesoporous magnesium oxide whose specific surface area range from 80 m²/g to 181.6 m²/g and aperture range from 3.6⁹.8 nm is obtained. The influences of different doping-ion such as Li⁺, Cu²⁺, Al³⁺, and Ti⁴⁺ on the specific surface area and antibacterial performance were investigated.更多还原
