摘要:
采用水热法合成金属有机骨架材料MIL-101。考察晶种、Cr源及矿化剂对合成的影响。利用X线粉末衍射仪(XRD)、比表面积及孔隙分析仪对合成材料进行表征。结果表明:直接水热法合成的材料Brunauer-Emmett-Teller(BET)比表面积为3 295 m2/g,产率为38.46%。加入晶种后能大大改善合成材料的质量,比表面积及产率都有很大幅度的提高,晶种量为12.2%时样品最优,比表面积为3 602 m2/g,产率为77.06%。Cr2(SO4)3作为Cr源时不能合成目标产物,Cr(NO3)3及CrCl3作为Cr源在不同矿化剂下均能合成目标产物MIL-101,并且Cr(NO3)3作为Cr源不加矿化剂条件下合成的样品最优,比表面积为3 234 m2/g,产率为68.20%,产率较直接水热合成的样品有很大的提高。
Abstract:
Metal-organic framework MIL-101 was synthesized by a hydrothermal method.Effects of seed,chromium resource,and mineralizing agent on the synthesis were investigated.The synthetic materials were characterized by X-ray powder diffraction(XRD)and specific surface area.Results showed that the samples by direct hydrothermal synthesis had a low yield,and Brunauer-Emmett-Teller(BET)specific surface area was 3 295 m2/g,the yield of 38.46%.But the adding of seed could improve the quality of synthetic materials with higher specific surface area and the yield.The best one was the specific surface area of 3 602 m2/g,and the yield of 77.06% with the adding seed of 12.2%.At the same time chromium sulfate hexahydrate as a chromium source could not synthesize the target product,chromium nitrate nonahydrate and chromium chloride hexahydrate as chromium source could synthesize the target product in different mineralizing agents with the optimal specific surface area of 3 234 m2/g, and the yield of 68.20%.
