A superhydrophobic BiOBr/Ag(3)PO(4) fabric was prepared to treat diverse pollutants, achieving high efficiency in removing oil pollutants and aqueous phase pollutants separately, with good mechanical stability and UV shielding performance for potential environmental applications.
Various forms of pollutants discharged from industrial and life; how to treat the opposite water-soluble pollutants at the same time is a challenge. Here, a superhydrophobic BiOBr/Ag(3)PO(4)fabric (SH fabric) bulk material was prepared aiming at the diversity of pollutants. Water (WCA=160 degrees) and oil contaminants (spread) have different wetting behavior on fabric surfaces. The high recovery efficiency for oil pollutants was achieved by using the selective oil removal property of the SH fabric. Meanwhile, the pollutants in the aqueous phase were removed by photocatalyst after oil/water separation. Mechanism analysis demonstrated that the direct Z-type heterojunction formed between BiOBr (E-VB=1.66 eV;E-CB=-1.08 eV) and Ag3PO4(E-VB=3.03 eV;E-CB= 0.6 eV). It is worth noting that the SH fabric exhibited good mechanical stability and UV shielding performance, which have potential application in environmental control.
