Ferric iron loaded porphyrinic zirconium MOFs on corncob for the enhancement of diuretics extraction

Atomically Fe‐anchored MOF‐on‐MOF nanozyme with differential signal amplification for ultrasensitive cathodic electrochemiluminescence immunoassay

“…After the Fe 3+ anchoring, the peak shifted positively to 396.7 eV due to the coordination between N and Fe 3+ and the charge‐oriented transfer from N to Fe 3+ . [ 32 ] This effect was also identified by fluorescence quenching of the system after the introduction of Fe 3+ on account of the fluorescence inner filter effect (IFE) and Förster resonance energy transfer (FRET, Figure 3C and Figure S6). Moreover, the PCN‐224/Fe showed obvious Fe─N at the wavelength of 997 cm −1 and the N─H at 3310 cm −1 disappeared in comparison with PCN‐224 and TCPP, demonstrating the atom anchoring of Fe with PCN‐224 by Fe─N bonds (Figure 3D and Figure S2).…”

[ 32 ] The peak at 1050 cm −1 is attributed to deformation peak of pyrrole. After the formation of PCN‐224 and anchoring of Fe with PCN‐224 by Fe─N bonds, the variation of charge density distribution may cause a change in the dipole moment of C─N, which resulted in the increased peak at 1050 cm −1 .…”

Post-synthesis modification of metal–organic frameworks: synthesis, characteristics, and applications

“…169 Studies demonstrated that post-synthetic MOFs were promising to be applied as drinking water cleaners for water purication. [170][171][172][173] UiO-66 porous liquids (PLs) synthesized by PSM from UiO-66-OH could efficiently adsorb CO 2 . 3 In the synthesis process of UiO-66 PLs, the as-synthesized UiO-66-OH was rst reacted with organosilane SIT to generate an intermediate product of SIT@UiO-66.…”

Metal-porphyrinic framework nanotechnologies in modern agricultural management

“…77 In parallel, eco-friendly and biodegradable MOF-containing composite membranes designed for slow delivery of herbicides upon membrane decomposition have also been prepared and investigated. 78 Other examples include composites of cellulose (CelloMOFs), 79 cotton 80 and corncob 81 used for the adsorption and extraction of pesticides. These composites have the advantage of addressing organic molecules regardless of the nature of the samples (in water, complex solids, and soil).…”
