New insight on interfacial charge transfer at graphitic carbon nitride/sodium niobate heterojunction under piezoelectric effect for the generation of reactive oxygen species.

Piezocatalytic removal of metronidazole (MET) using graphitic carbon nitride (g-CN, GCN)/sodium niobate (NaNbO) heterojunction was investigated under ultrasonication. Herein, optimized GCN(50)/NaNbO heterojunction achieved 87.2% MET removal within 160 min (k = 0.

Single and multi-antibiotics removal via peroxymonosulfate activation using molybdenum disulfide (MoS): Central composite design and degradation pathway.

The efficacy of molybdenum disulfide (MoS) for the degradation of metronidazole (MET), tetracycline (TET), and ciprofloxacin (CIP) in single and multicomponent systems through peroxymonosulfate (PMS) activation was investigated. Several characterization techniques, such as SEM, XRD, XPS, and EPR were performed to understand the removal mechanism of the three antibiotics in PMS/MoS system. In single component system with an initial antibiotic concentration of 10 mg L, >95% removal of MET, TET, and CIP were observed within 60 min (PMS = 100 mg L; MoS = 0.

Facile synthesis of graphitic carbon nitride from acetic acid pretreatment to activate persulfate in presence of blue light for photocatalytic removal of metronidazole.

Activation of persulfate (PS) in presence of blue LED light (λ ∼454 nm) using acetic acid modified graphitic carbon nitride (ACN) was investigated. Usage of acetic acid had improved the specific surface area (SSA, 21.89 m g) of ACN compared with pristine graphitic carbon nitride (GCN) and it also reduced interfacial charge transfer resistance in ACN.
