Visible-light-driven removal of tetracycline hydrochloride and microplastics (HDPE) by nano flower hybrid heterojunction NH2-MIL-88B(Fe)/MoS2 via enhanced electron-transfer

Fe–Co-Based Metal–Organic Frameworks as Peroxidase Mimics for Sensitive Colorimetric Detection and Efficient Degradation of Aflatoxin B1

“…The band at 521 cm –1 originated from the tensile vibration of the Fe–O–Fe bond . What is more, two wide peaks at 3460 and 3375 cm –1 presented the asymmetric and symmetric stretching vibration of N–H, and the band at 1652 cm –1 was caused by the bending vibration of N–H, fully confirming the existence of −NH 2 in Fe–Co-MOFs, which is favorable for the biomolecule conjugation. In addition, the energy-dispersive spectrometry (EDS) spectra and element mapping confirmed that the C, N, O, Fe, and Co elements were evenly distributed within the material (Figure S5 and Figure D).…”

Photocatalytic degradation of different types of microplastics by TiOx/ZnO tetrapod photocatalysts

“…6 . It is known that the dominant reaction during photodegradation of plastics is photooxidation, and that the generation of ROS, though rarely studied [ 20 , [22] , [23] , [24] , [25] , [26] ], plays a role in the degradation process [ 18 , 22 ]. The ROS in aqueous solutions containing photocatalyst are generated from reactions of photogenerated electrons and holes with O 2 and OH − , and produced superoxide ion and hydroxyl radicals can then generate other reactive species such as H 2 O 2 [ 22 ].…”

“…Consequently, photodegradation processes including the effect of illumination and the effects of a number of different photocatalysts on degradation/chemical changes of different plastics have been investigated in recent years [ [17] , [18] , [19] , [20] , [21] , [22] , [23] , [24] , [25] , [26] , [27] , [28] , [29] , [30] , [31] , [32] , [33] , [34] , [35] , [36] , [37] , [38] , [39] , [40] , [41] , [42] , [43] , [44] ], and the results have been summarized in Table S1 . The degraded plastics include polyolefins, such as polyethylene (PE) and polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC) polyethylene terephthalate (PET), polyamide fibers, and poly(methylmethacrylate) [ 1 , 8 , 9 , 12 ].…”

Photocatalytic Removal of Polyester Polyurethane, and Polyethylene Microplastics via ZnO-Fe-Mg-C Nanocomposite to H2

“…ZnO nanocomposite exhibited elevated surface and high durability compared to other metal oxides. This, cause to an excellent photodegradation activity, [15]. In order to extend the photocatalytic yields of ZnO, nonmetals, and carbonated chemicals can be doped on ZnO surface to improve the activity of electrons in holes, [20].…”

“…Polyethylene contained low weight carbon benzene and can be generated from the degradation of ethylene, [11], [12], [13], [14], [15], [16], [17], [18]. Polyethylene is a resin from polyolefin group.…”
