“…Its structure contains two chlorine atoms and a phenolic hydroxyl group, which gives it unique chemical properties, complex composition and long-term persistence in the aqueous environment . Its inherent “triple hazard” poses a potential threat to the ecosystem and human health. − As a result, the environmental problem of 2,4-DCP has been gradually highlighted . According to the relevant literature, the COD of pesticide wastewater ranges from 150 to 750 mg/L and the BOD ranges from 30 to 599 mg/L .…”

The objective of this work is to develop a microsomal composite catalytic membrane that exhibits efficient catalytic capabilities and robust stability, thereby addressing the challenge of recycling and reusing powdered photocatalytic materials. Specifically, Bi 2 MoO 6 and WO 3 nanoparticles were incorporated onto polyurethane (PU) substrates using a hybrid in situ growth method. By forming Bi 2 MoO 6 /WO 3 heterojunctions, the photocatalytic activity of the membrane was enhanced without compromising its structural integrity. The flexibility and porosity of PUs play a crucial role in facilitating the adsorption of 2,4dichlorophenol (DCP) molecules on the membrane's surface, leading to the efficient degradation of contaminants through the cleavage of C−Cl bonds triggered by the migration of electron pairs generated by the photocatalysts. A 5 × 5 cm composite membrane was tested for degradation in 20 mg/L 2,4-DCP solutions with neutral pH, achieving a degradation rate of 78.8% within 120 min. The composite membrane exhibited stability after undergoing six cycles of testing, affirming the effectiveness of its composition. Furthermore, a detailed analysis was conducted on the photocatalytic reaction mechanism of 2,4-DCP on the WO 3 /Bi 2 MoO 6 /PU membrane surface, highlighting the potential of porous composite membranes for wastewater treatment.
