Water-based preparation of nano-sized NH2-MIL-53(Al) frameworks for enhanced dye removal

Nano-sized NH 2 -MIL-53(Al) particles were conveniently synthesized in aqueous solution at ambient temperature with a widely applicable mixing method, and the morphology and character were examined with a series of techniques. XRD patterns and TEM images showed that the obtained NH 2 -MIL-53(Al) material possessed rod-like shape, which is different from those obtained from N, N-dimethyl formamide (DMF). This nano-sized NH 2 -MIL-53(Al) matrix displayed enhanced efficiency for adsorptive elimination of methyl blue molecules in aqueous solution.
