Water pollutions that come from spilled oils,discharged organic reagents and abused pesticides have become an urgent problem to ecosystem.In this study,inspired by the multi-properties of MOF materials,we presented a bifunctional MOF-based sponge(OPA-UiO-66@MF)to achieve the effective oil/water separation as well as the catalytic degradation of organic pollutants.On one hand,upon the in-situ growth of UiO-66 on melamine foam(MF)sponges and the octadecyl-phosphonic acid(OPA)modification of UiO-66,we highlighted the super-hydrophobic/superoleophilic property of the OPA-UiO-66@MF,which leads to excellent performances in oils adsorption and continuous oil/water separation.On the other hand,benefits from the lipase-like property of UiO-66,OPA-UiO-66@MF was proved having potential ability in the catalytic degradation of carboxylic acid ester pesticides which are usually enriched in oils or organic solvents.Moreover,since phosphorus containing groups can be introduced onto the surface of sponge through OPA modification,OPA-UiO-66@MF also displayed superior flame resistance.As an effective,safe and green material,the developed flame-resistant bifunctional OPA-UiO-66@MF sponge might provide a promising application in the elimination of organic pollutants in water systems.
