Abstract
In this work, a novel S-scheme Bi2WO6@NH2-MIL-125(Ti) heterojunction composite was synthesized for the first time by a secondary hydrothermal method. XRD, SEM, TEM, XPS and DRS were used to characterize the Bi2WO6@NH2-MIL-125 (Ti) composite. The results show that NH2-MIL-125(Ti) is embedded between Bi2WO6 nanosheets, the composite materials have narrower bandgap and enhanced absorption of visible light. The recombination tendency of electron–hole pairs were also weakened by the S-scheme heterojunction between the two monomers. The best content of NH2-MIL-125(Ti) was 13 wt%, the degradation rate of RhB reached 98% in 50 min, which was 5 times and 18 times that of the Bi2WO6 and NH2-MIL-125 (Ti) respectively. After several cycles under visible light, the composite materials still have good degradation rate and excellent stability, indicating that these composite materials have great development potential in the environmental field.
