Zinc indium sulfide (ZnIn2S4)/MIL-125 composites were synthesized by a two-step hydrothermal method. The effect of ZnIn2S4 on the phase, morphology, chemical state, spectral response and photocatalytic performance of the composite was evaluated in detail. The results show that a small amount of ZnIn2S4 results in the morphological evolution of MIL-125 from discoid block to pie shape, and a gradual decrease of the specific surface area. The photocatalytic degradation activity towards rhodamine B dye is greatly improved at the optimal ratio of 0.8% (in mole fraction). The degradation efficiency for the composite is 97.7% while the degradation efficiency for pure MIL-125 is only 70.3% within 50 min. It is indicated that a small amount of ZnIn2S4 suppresses the carrier recombination and improves the carrier transport, finally resulting in the enhancement of photocatalytic activity. In addition, the possible mechanism is also proposed.
