The recent advances of MnFe2O4-based nanoparticles in environmental application: A review

The manganese ferrite (MnFe2O4)-based nanoparticles showed a substantial potential to remediate the various pollutants in environmental application due to low cost, simple magnetic separation and high removal capacity. Herein, the functionalization of various MnFe2O4-based nanoparticles was briefly summarized; Then the recent advances concerning the removal of pollutants (i.e., organics, heavy metals and antibacterial activity) on different MnFe2O4-based nanoparticles were reviewed in details. The reactivity of MnFe2O4-based nanoparticles was significantly influenced by environmental factors. It is demonstrated that interaction mechanism of various pollutants on magnetic MnFe2O4-based nanoparticles included degradation, adsorption, coordination, redox and precipitation. Finally, the current problems and future perspective of MnFe2O4-based nanoparticles were proposed. The highlight of this review is to compare the removal performance of MnFe2O4-based nanoparticles with the different hybrids. This review is crucial for the application of MnFe2O4-based nanoparticles in the environmental remediation.
