The applications of traditional photo-Fenton reaction are mainly limited by the low photo generated electron concentration, resulting in the low Fe3+/Fe2+ conversion efficiency and low concentration of reactive oxygen specious (ROS). In this study, a mesoporous TiO2 single crystal decorated by platinum (Pt) nanoparticles and molybdenum disulfide (MoS2) hybrid Z-scheme system (Pt-MSCs@MoS2) is successfully synthesized for efficiency synchronous REDOX. The construction of Z-scheme composite leads to the consumption of photo-generated hole (h + ) and prolongs the lifetime of the electrons (e(-)) of MoS2, so as to ensure that the MoS2 is exposed with Mo4+ active sites and exhibits high efficiency for Fe2+/Fe3+ cycling. The high Fe2+/ Fe3+ ratio of Z-scheme photo-Fenton system is conducive to the decomposition of hydrogen peroxide (H2O2) to produce more OH. High concentration of photo-generated e - with high reduction potential is conducive to the reduction and recovery of various metal ions, such as Cr6+, Ag+ , Cu+ and Ni+ . Therefore, the Z-scheme photo-Fenton system shows strong synchronous REDOX performance for removal of different emerging organic contaminants and recovery of different metal ions. The reasonable mechanism of Z-scheme photo-Fenton system and oxidation pathway of carbamazepine (CBZ) were investigated by experimental analysis and molecular orbital calculation. The toxicities of CBZ and its oxidation intermediates in Z-scheme photo-Fenton systems were compared by Toxicity Estimation Software (T.E.S.T.) based on quantitative structure-activity relationship (QSAR). This Z-scheme provides a high efficiency synchronous REDOX strategy for wastewater treatment.

We investigated the outcome of altering antiepileptic drug (AED) therapy in the year before pregnancy on 2233 occasions in Australian women in the 20-year period of functioning of the Raoul Wallenberg Australian Pregnancy Register (APR). Therapy had been altered in 358 instances (16%) in the months prior to the pregnancy (median interval: 18 weeks). Antiepileptic drug doses had been changed in 141 pregnancies (39.4%), being decreased in 94; drugs changed in 151 (42.2%); drugs withdrawn without replacement in 66 (18.4%) but resumed in 40 before pregnancy ended. The main drugs involved were valproate (34%), phenytoin (16.5%), topiramate (12.6%), and carbamazepine (11.4%). Antiepileptic drug doses were increased significantly more often (16.9% vs. 6.4%) when epilepsy before pregnancy was not controlled, and AED treatment ceased significantly less often (13.6% vs. 24.0%). The alterations were more often made in women with generalized epilepsies and in those whose seizure disorders were not fully controlled in the prepregnancy year, suggesting that avoidance of teratogenicity and achieving improved seizure control often motivated the changes. Overall, the alterations did not result in improved rates of seizure freedom during pregnancy, as compared with pregnancies where therapy was unchanged; however, fetal malformation rates were lower 3.6% vs. 5.4%, but this difference did not attain statistical significance. The same trends regarding seizure control and malformations persisted after pregnancies involving valproate exposure were excluded. In conclusion, this analysis of the APR cohort did not demonstrate that altering AEDs before pregnancy produced a significant improvement in seizure control and the reduction in fetal malformation rate that occurred was not statistically significant.
