Abstract
Insufficient water stability is an important problem restricting the practical application of metal–organic frameworks (MOFs) in the field of volatile organic compounds (VOCs) adsorption. In this work, a copper(II) benzene-1,3,5-tricarboxylate MOF (Cu-BTC)/biochar composite with improved water stability was obtained by a facile one-pot method for toluene adsorption applications. Different from the traditional regular octahedral configuration, Cu-BTC was scattered on biochar in the form of broccoli-shaped microspheres. The influence of humid air aging on the physiochemical and toluene adsorption properties of Cu-BTC and Cu-BTC/biochar composites under different periods were explored. The results show that the inner structure of Cu-BTC degrades with the micropores transformed into meso-macropores under the humid air aging. Moreover, the BET surface area was reduced by 63.2 % and 94.7 % after 3-month and 6-month aging, respectively, which could eventually lead to a serious decline (76.3 % and 96.5 %) in the adsorption capacities of toluene. It can also be found that compared to traditional octahedral Cu-BTC, the degradation process of broccoli-shaped Cu-BTC/biochar is effectively slowed down, which shows better moisture stability. The retention rates of toluene adsorption capacities for broccoli-shaped Cu-BTC/biochar were 57.7 % and 17.1 % after 3-month and 6-month aging, respectively. This study is helpful for better improving the water stability of MOFs materials used for VOCs adsorption.
