Fabrication of PVDF-based piezocatalytic active membrane with enhanced oxytetracycline degradation efficiency through embedding few-layer E-MoS2 nanosheets

Boosting photocatalytic removal of organic pollutants through enhanced piezoelectricity in free-standing nanofibril pyridyl-functionalized conjugated microporous polymer/poly(vinylidene fluoride–trifluoroethylene) hybrids

“…11,12 For instance, Sn 3 O 4 /PVDF hybrids have been reported to show highly effective photodegradation of organic pollutants, which is ascribed to the water-flow driven piezotronics effect that arises from the ferroelectric nature of PVDF. 13 Similar results were also achieved in piezo-photocatalysts of TiO 2 @rGO-F/PVDF-HFP cushions, 14 exfoliated multi-flaw MoS 2 /PVDF electro-spun fiber films, 15 ZnS/Bi 2 S 3 –PVDF composite films, 16 etc. Although great progress has been achieved, the exact correlation between the electronic structure and catalytic properties of piezo-photocatalysts is still ambiguous, which is fundamental to the rational design and fabrication of new materials with tunable piezo-photocatalytic activities for a wide range of applications.…”

A highly dispersed magnetic polymetallic catalyst to activate peroxymonosulfate for the degradation of organic pollutants in wastewater

“…6c, a characteristic 1 : 1 : 1 triplet peak of TEMP-1 O 2 was detected in the PMS-only system, which was generated by the PMS self-decomposition. 54 In addition, the signal intensity of 1 15)). 57 Subsequently, A(III) could be reduced by HSO 5 − , achieving the interconversion of A(II) and A(III) (eqn ( 16)).…”

“…Antibiotics make significant contributions to the prevention and treatment of human diseases, livestock diseases and bacterial infections. 1,2 Oxytetracycline (OTC), one of the most common broad-spectrum antibiotics, has been widely applied in human life, animal husbandry and aquaculture. 3,4 However, most tetracycline (TC)-group antibiotics are difficult to metabolize in organisms, and almost half of them are released into natural water systems.…”

Peroxymonosulfate activation by Co-doped magnetic Mn3O4 for degradation of oxytetracycline in water

“…At present, there have been many reports on the methods of removing OTC from water bodies. At present, the methods to remove oxytetracycline from water mainly include physical adsorption [16], Fenton -like oxidation [17], electrochemical catalytic oxidation [18], photocatalysis [19], etc. Sulfate radical-based advanced oxidation processes (SR-AOPs) are widely used for oxidizing and degrading pollutants [20].…”
