Polyoxometalate@MIL-101/MoS2: a composite material based on the MIL-101 platform with enhanced performances

Abstract

A composite was designed and synthesized based on MIL-101, MoS2, and an iron-substituted polyoxometalate. MoS2 and PW11O39Fe(H2O)4− (PW11Fe) were introduced on the surface of MIL-101 and encapsulated in the cages of MIL-101, respectively. First, a facile microwave synthesis method was developed for synthesizing the composite MIL-101/MoS2. Then, PW11Fe clusters were diffused into the pores of MIL-101/MoS2. The composite PW11Fe@MIL-101/MoS2 could rapidly adsorb rhodamine B (RhB). An adsorption capacity of 378 mg g−1 was achieved in the first 5 min. Moreover, PW11Fe@MIL-101/MoS2 could be potentially used for the separation of dyes. Its RhB adsorption capacity at equilibrium was about four times higher than that of MIL-101. In contrast, its methyl orange (MO) adsorption capacity was about three times lower than that of MIL-101.
