Cooperative assembly of 2D‐MOF nanoplatelets into hierarchical carpets and tubular superstructures for advanced air filtration

Clean air is an indispensable prerequisite for human health. The capture of small toxic molecules requires the development advanced materials filtration. Two-dimensional nanomaterials offer highly accessible surface areas but real-world applications their assembly into well-defined hierarchical mesostructures essential. DUT-134(Cu) ([Cu2(dttc)2]n, dttc=dithieno[3,2-b : 2′,3′-d]thiophene-2,6-dicarboxylate]) a metal–organic framework forming platelet-shaped particles, that can be organized complex structures, such as millimeter large free-standing layers (carpets) and tubes. structured material demonstrates enhanced accessibility open metal sites significantly H2S adsorption capacity in gas filtering tests compared with traditional bulk analogues.
