Novel MoS2/BaSO4/zeolite heterostructure composite for the enhanced visible-light photocatalytic degradation of sulfadiazine
Abstract Molybdenum disulfide (MoS2) can be used as a potential photocatalyst for the removal of emerging contaminants (ECs) under visible light (Vis). However, the high carrier recombination rate and aggregation restrict pure MoS2 application. The hydrothermal method was used to prepare a novel MoS...

| description | Abstract Molybdenum disulfide (MoS2) can be used as a potential photocatalyst for the removal of emerging contaminants (ECs) under visible light (Vis). However, the high carrier recombination rate and aggregation restrict pure MoS2 application. The hydrothermal method was used to prepare a novel MoS2/BaSO4/zeolite (Z) composite (MBZ), which was used to activate peroxymonosulfate (PMS) under visible light for sulfadiazine (SDZ) degradation. The MBZ showed a moderate E g value (2.59 eV), indicating good visible-light absorption. The physicochemical and photoelectrochemical properties were analyzed, revealing that the hybrid MBZ significantly enhanced photoinduced carrier generation, separation, and transfer. The MBZ exhibited 2.38-, 3.24-, and 1.36-fold higher SDZ removal reaction rates than Z, BaSO4, and MoS2 in the PMS/Vis system. The addition of EDTA-2Na notably decreased the degradation rate (79.58–89.88%), indicating the significant role of h + . This work provides a new approach to the design of semiconductor/insulator photocatalysts and constructs a promising catalytic oxidation system for the green remediation of EC wastewater. |
