Stable hierarchical microspheres of 1D Fe–gallic acid MOFs for fast and efficient Cr(vi) elimination by a combination of reduction, metal substitution and coprecipitation

Abstract

One-dimensional Fe–gallic acid MOFs were assembled into stable hierarchical microspheres in DMF solvent taking advantage of DMF decomposition by heat. The rapid electron transfer ability and high accessibility of the multiple reaction sites on Fe–gallic acid microspheres ensure fast and complete elimination of Cr(VI) from water samples.
