Performance of iopamidol degradation by MoS2@Fe3O4 Fenton-like system
MoS2@Fe3O4 composite was fabricated via two-step hydrothermal method, utilizing cetyltrimethyl ammonium bromide(CTAB) as a soft template, thioacetamide as a sulfur source, and sodium molybdate as a molybdenum source. The morphology and structure of MoS2@Fe3O4 were analyzed by SEM and XRD. The effici...

| description | MoS2@Fe3O4 composite was fabricated via two-step hydrothermal method, utilizing cetyltrimethyl ammonium bromide(CTAB) as a soft template, thioacetamide as a sulfur source, and sodium molybdate as a molybdenum source. The morphology and structure of MoS2@Fe3O4 were analyzed by SEM and XRD. The efficiency and mechanism of catalytic degradation of iodoprolol(IPM) by MoS2@Fe3O4/H2O2 system was evaluated. The results showed that Fe3O4 was deposited on the surface of MoS2, and MoS2@Fe3O4 had a uniformly dispersed flower ball structure, which provided more catalytic active sites. Under the conditions of initial pH of 4, MoS2@Fe3O4 dosage of 0.15 g/L, H2O2 concentration of 0.5 mmol/L, and IPM concentration of 5 μmol/L, the degradation rate of IPM by MoS2@Fe3O4/H2O2 system reached 89.85% after 30 minutes of reaction. Compared with Fe3O4/H2O2 system, the degradation rate of IPM increased by about 12%. The applied magnetic field facilitated the reusability of MoS2@Fe3O4. The main active species for IPM degradation by the MoS2@Fe3O4/H2O2 system were ·OH and 1O2. The degradation rate of the MoS2@Fe3O4/H2O2 system on IPM remained stable over 80% after 6 cycles, suggesting that MoS2@Fe3O4 had good stability. |
