Synthesis of novel CuFe2O4/MIL-53(Fe)/MoS2 ternary heterojunction nanocomposite sonocatalytic for the degradation of organic dye pollutants

Supporting of CuFe2O4 nanoparticles and MIL-53(Fe) metal organic framework on the MoS2 nanoflowers were successfully carried out to enhance the sonocatalytic activity using a facile ultrasonic-assisted hydrothermal route. The FESEM/EDAX, XRD, FTIR, VSM, and BET were used to characterize the nanocomposite. The as-synthesized CuFe2O4/MIL-53(Fe)/MoS2 sonocatalyst nanocomposite revealed a relatively high sonocatalytic activity than CuFe2O4, MIL-53(Fe) and MoS2 under H2O2-ultrasonic (US) system for the degradation of organic dye pollutants, including methylene blue (MB), rhodamine B (RhB) and methyl orange (MO). Besides, the impact of several parameters such as contact time, catalyst dosage, initial concentration of MB, H2O2 concentration, organic dye type, and process type on the degradation reactions of MB, RhB, and MO were implemented. The obtained outcomes displayed that the CuFe2O4/MIL-53(Fe)/MoS2 sonocatalytic can be degrade the MB dye (25 mg/L) up to 98.9%. The •OH free radicals were also recognized as the main reactive oxygen species within the MB sonodegradation reaction. Additionally, the results of the recyclability investigation of the CuFe2O4/MIL-53(Fe)/MoS2 sonocatalytic obviously illustrated a less than 5% drop of the catalytic performance up to five sequential cycles. Ultimately, a proposed mechanism for the sonodegradation process of organic dyes was suggested and discussed.
