摘要 以硝酸铝和对苯二甲酸为反应物,采用水热合成法制备MIL-53(Al),并采用调制协同法,分别以甲酸钠和三乙胺为添加剂,利用其去质子化和结构封端剂的协同作用对晶体尺寸和形貌进行调控。通过适量甲酸钠的添加成功制备了粒径均匀的纳米晶,且该材料具有很高的热稳定性和高比表面积。 MIL-53(Al)was synthesized with aluminum nitrate and terephthalic acid by hydrothermal method.The crystal size and morphology were regulated by modulation coordinative method with sodium formate and triethylamine as additives which taking advantage of the synergistic effect of disprotonation and capping agent.Accompanied with appropriate amount of sodium formate,nano MIL-53(Al)with uniform dimension was successfully prepared.The material had high thermal stability and high surface area.
