Based on the magnetic sensitivity of Fe3O4 in various fields, we aimed to propose a one-step solvothermal process for synthesis single-phase induced by reaction medium and urea, avoiding high-temperature reduction H2 or N2 atmospheres. Feasibility was tested with purified water (H2O), methyl alcohol (MA), ethyl (EA), ethylene glycol (EG) as media. The findings indicated that system utilizing EA more effective cubic Fe3O4. Optimal conditions synthesizing pure were obtained optimizing urea amount parameters. optimal formulation consisted 10 mmol FeCl3, 80 60 mL subjected at 200 °C 12 h. resulting (magnetite, cubic) exhibited commendable crystallization morphology acicular aggregates displayed excellent properties magnetization 92.2 emu/g 15,000 Oe. photocatalytic degradation behaviors Methyl Orange, Orange G, Acid Red 37 azo dyes repeated performance dye investigated. Nearly complete occurred after 2.0 h reaction, while G achieved similar results 3.5 4.5 h, respectively. exploration strategy this work can be applied design fabricate other metal oxides composites, potentially novel discoveries performance.
