Abstract： The phosphotungsticacid PW12 loaded manganese-based metal organic frameworks composites PW12@Mn -dhbq were prepared by hydrothermal method， their morphology and structures were characterized by XRD， SEM， XPS，FTIRandother characterization means，and Fenton-like properties of the composites were tested byusing methylene blue as the target degradation agent. The results showed that the addition of PW12 greatly enhanced the Fenton-like performance of the material， and the degradation rate of 20mg⋅L-1 MB by PW12@Mn -dhbqcouldreach 78.24% in 60min when the dosage of PW12@Mn -dhbq was 20mg and the dosage of H2O2 was 70μL ，which could provide new ideas for using heteropolyacid-loaded Mn-based MOFs as non-homogeneous phase-like Fenton catalysts for the degradation of dye wastewater.
