“…For system ④, the degradation rate of 2,4-DCP reaches 96.3%, which is much higher than that of other systems, indicating that for the Fe3O4/α-MnO2 MNCs prepared by the hydrothermal synthesis method and the ultrasonic coprecipitation method, the activation capacity is significantly improved, and the activation performance is much better than that of the systems ① (Fe3O4 MNPs alone), ② (α-MnO2 nanowires alone) and ③ (mixture of Fe3O4 and α-MnO2), indicating that there is a synergistic catalytic effect between Fe3O4 and α-MnO2 in the MNCs. Similar synergistic effects due to electron transfer have been found in other studies [40,41]. In addition, in the process of multiple recycling and reuse cycles, the Fe3O4/α-MnO2 MNCs still maintain high activation performance, indicating that in the process of activating PS to degrade pollutants, the leaching effect is limited, and the reaction mainly occurs on the surface of the MNCs.…”

“…10 Thus, in recent years, with the booming development of semiconductor and photoelectric chemistry technology, photocatalysis as a novel and efficient wastewater purification technology has been increasingly favored and studied by researchers. 11 Currently, many photocatalysts have been exploited for organic pollutant degradation, 12 heavy metal ion removal, 13 CO 2 reduction and water splitting, 14,15 etc., including metal oxides 16,17 such as Fe 2 O 3 , Cu 2 O, and Bi 2 O 3 , metallic sulfides 18,19 such as CdS and MoS 2 , bismuth-based photocatalysts, 20 silver-based photocatalysts, 21 g-C 3 N 4 , and metal organic frameworks. 22 Among the semiconductor catalysts, metal-organic frameworks (MOFs) are typical porous inorganic-organic hybrid materials.…”
