(a) Schematic illustration of the proposed mechanism on photocatalytic reduction of U(VI) for TCPP(Ni)⊂MOF-3 [128], and (b) NZVI@PCN-224 [130]. (c) Stability and antibacterial activity of BP@CNF-MOF after exposure to natural seawater for 0, 15, and 30 days [133]. (d) Proposed mechanism on photocatalytic reduction of U(VI) for Ti-MOF@DATp [134], (e) POMOF and (f) Cu@Th-TCPP [136]. (g) SEM images (scale bar, 5 μm) of the AOP@ZIF-8/TA fibers after each elution [137].
