【摘要】：在不添加氫氟酸的條件下,以九水合硝酸鐵和1,3,5-均苯三甲酸(H3BTC)為原料,用水熱合成法制備了多孔鐵的三聚物金屬有機骨架材料(Fe-MIL-100)。采用XRD、BET、SEM、FT-IR和TG等手段表征Fe-MIL-100樣品的結晶度、比表面積、形貌和熱穩(wěn)定性,研究了晶化過程中晶化溫度、HNO3添加量、晶化時間以及后處理條件對Fe-MIL-100材料結構的影響。優(yōu)化合成工藝條件后,制備出結晶度較高、熱穩(wěn)定性優(yōu)異、比表面積可達1744 m2/g、在氮氣氛下熱分解溫度可達520℃的Fe-MIL-100材料。
[Abstract]:In the absence of hydrofluoric acid, the porous iron trimer metal organic skeleton material (Fe-MIL-100) was prepared by hydrothermal synthesis from ferric nitrate nine hydrate and H3BTC1 (1) 3H _ (3) O _ (3) phthalate. The crystallinity of Fe-MIL-100 samples was characterized by means of XRDX BETX SEMFT-IR and TG, etc. The specific surface area, morphology and thermal stability were studied. The effects of crystallization temperature, amount of HNO _ 3, crystallization time and post-treatment conditions on the structure of Fe-MIL-100 were studied. Fe-MIL-100 materials with a specific surface area of 1744m2 / g and a thermal decomposition temperature of 520 鈩，
