Metal organic framework-activated carbon composite material as well as preparation method and application thereof

The invention provides a metal organic framework-activated carbon composite material as well as a preparation method and application thereof. A metal organic framework is positioned in a pore channel of activated carbon; the aperture of the metal organic framework is 1.5 to 5 nm; the metal organic framework-activated carbon composite material is of a mesoporous structure. According to the invention, the metal organic framework adsorbent with a specific aperture range is introduced into the activated carbon, and through structural regulation and control of the two, on one hand, the effect of macropores in the activated carbon is reduced through an occupation effect, and on the other hand, the adsorption quantity and desorption efficiency of butane are improved by utilizing the unique pore structure of the metal organic framework adsorbent. 本发明提供了一种金属有机框架-活性炭复合材料及其制备方法和应用，所述金属有机框架位于所述活性炭的孔道中；所述金属有机框架的孔径为1.5-5nm；所述金属有机框架-活性炭复合材料为介孔结构。本发明通过在活性炭中引入特定孔径范围的金属有机框架吸附剂，通过二者的结构调控，一方面通过"占位"效应缩小活性炭中大孔的效应，另一方面利用金属有机框架吸附剂独特
