- Aerobic Alcohol Oxidation by a Zeolitic Octahedral Metal Oxide based on Iron Vanadomolybdates Under Mild Conditions
-
Zeolitic octahedral metal oxides are fully-inorganic crystalline materials with the multi-component redox property and the intrinsic microporosity. The redox active zeolitic iron vanadomolybdate acts as a catalyst for aerobic oxidation of primary aromatic alcohols. Molecular oxygen is able to be activated in the material due to the confinement effect of the micropore and the unique redox property of the framework. Different primary aromatic alcohols are oxidized by the material, and high alcohol conversion and aldehyde selectivity are achieved. The material is stable and able to be reused for 5 times without loss of activity.

- Degradation of ciprofloxacin with hydrogen peroxide catalyzed by ironmolybdate-based zeolitic octahedral metal oxide
-
Ciprofloxacin, a widely used fluoroquinolone antibiotic, is found in drinking water as a pseudo-persistent pollutant. Zeolitic octahedral metal oxide based on ε-Keggin ironmolybdate (MoFeO) is synthesized as an efficient catalyst for ciprofloxacin degradation with H2O2. Higher than 80% of ciprofloxacin is degraded in the pH range from 5 to 8, and the highest degradation percent is achieved at pH 8. The catalyst shows high stability as a heterogeneous catalyst and can be reused up for 3 times in continues ciprofloxacin degradation. Presence of humic acid has no effect on the ciprofloxacin degradation catalyzed by MoFeO, and ciprofloxacin is efficiently degraded in the water from city tap, river, pond, lake, and sea with various dissolved organic matter concentrations and conductivities.
