金属有机骨架材料mil-101的合成及co吸附性能
, PP. 7-11
Keywords: mil-101,吸附等温线,巨正则蒙特卡洛模拟方法,孔径分布,co
Abstract:
采用水热法合成金属有机骨架材料mil-101,并利用x线衍射(xrd)、低温n2吸附等测试手段对合成的材料进行表征。结果表明:制备的mil-101的bet(brunauer-emmett-teller)比表面积达到3142m2/g,孔容为1.78cm3/g。根据77k下n2吸附等温线数据,采用巨正则蒙特卡洛法分析mil-101的孔径分布,其分析结果与文献所报道的数据吻合。考察了co、n2混合体系在mil-101上的吸附性能,实验结果表明:mil-101结构中不饱和金属cr3+提供的活性位能从混合气体中高效吸附分离co,而且对co的吸附容量达到45.0cm3/g(298k,0.1mpa),对co的吸附容量约是na吸附剂的2倍。
