Zinc-tetracarboxylate framework material with nano-cages and one-dimensional channels for excellent selective and effective adsorption of methyl blue dye

An example of a zinc-tetracarboxylate framework material (FJI-11) was solvothermally synthesized and structurally characterized. FJI-11 presented 3D cage-stacking frameworks with octahedral cages, cuboctahedral cages and two kinds of 1D channel along the c-axis. In addition, FJI-11 exhibited the excellent selective and effective adsorption of methyl blue (MB) dye by guest molecule exchange, and its adsorption process was in accordance with the second-order kinetic model and the Freundlich model.
