Superoxide radical mediated persulfate activation by nitrogen doped bimetallic MOF (FeCo/N-MOF) for efficient tetracycline degradation

A Co@C Catalyst Derived from a Cobalt‐Based Metal Organic Framework with Enhanced Activation of Peroxymonosulfate for Degradation of Organic Pollutants

“…Moreover, TEMPO was utilized as a trapping agent for 1 O 2 capture. [37] As illustrated in Figure 8b, strong characteristic peaks assigned to the TEMPO-1 O 2 was observed in the Co@C/PMS system. The EPR results were in line with the results of the aforementioned quench tests, indicating that both the radical and the nonradical routes were used to degrade TC in the reaction.…”

“…Figure 8a and 8c demonstrates that the typical characteristic peaks associated with DMPO‐$${{{\rm { SO}}}_{{\rm { 4}}}^{{\rm { \bullet -}}}}$$ , DMPO‐$${{{\rm { \bullet O}}}_{{\rm { 2}}}^{{\rm { -}}}}$$ and DMPO‐$${{\rm { \bullet }}}$$ OH have been detected, demonstrating the existence of $${{{\rm { SO}}}_{{\rm { 4}}}^{{\rm { \bullet -}}}}$$ , $${{{\rm { \bullet O}}}_{{\rm { 2}}}^{{\rm { -}}}}$$ and $${{\rm { \bullet }}}$$ OH in the Co@C/PMS catalytic system. Moreover, TEMPO was utilized as a trapping agent for $${{}_{{\rm { \ }}}{}^{{\rm { 1}}}{{\rm { O}}}_{{\rm { 2}}}^{{\rm { \ }}}}$$ capture [37] . As illustrated in Figure 8b, strong characteristic peaks assigned to the TEMPO‐$${{}_{{\rm { \ }}}{}^{{\rm { 1}}}{{\rm { O}}}_{{\rm { 2}}}^{{\rm { \ }}}}$$ was observed in the Co@C/PMS system.…”

A portable test strip fabricated of luminescent lanthanide-functionalized metal–organic frameworks for rapid and visual detection of tetracycline antibiotics

“…The absorption peaks appearing at 671 and 1134 cm −1 were induced by out-of-plane and in-plane bending of the aromatic C–H stretching contained in the benzene ring of H 4 BTEC, respectively. 48 The reactive properties of free –COOH, combined with the perpetual porosity of UC, enabled it to be a favourable choice for binding with Tb 3+ and Ag + , which make it to be versatile in enhancing adsorption and detection performance of TCs. Subsequently, the morphology of the initial UC and ATUC was measured by scanning electron microscopy (SEM).…”

Characteristics and application of iron-based materials in heterogeneous Fenton oxidation for wastewater treatment: a review

“…Zr played a role in the catalytic reaction for electron transfer. Zhang et al 251 prepared a nitrogen-doped Fe, Co bimetallic MOF (FeCo/N-MOF) as a catalyst by a hydrothermal method to catalyze persulfate to degrade tetracycline. The characterization results showed that it has a hexagonal spindle crystal morphology and porous structure.…”

“…In addition to loading monometallics onto MOFs, some researchers have also loaded bimetallics onto MOFs, and the bimetallic facilitation improves the degradation efficiency. [157][158][159][160][248][249][250][251] Mn-doped magnetic lamellar pore and ionic liquid (IL) post-functionalized Zr-MOF composites (MFC@Mn-NH 2 -UiO-66@IL) were synthesized by Lu et al 248 The characterization results showed that the composites were laminar porous, which facilitated the adsorption process and the subsequent H 2 O 2 decomposition catalysis. During the catalytic degradation of MB, the electrostatic interactions, hydrogen bonding and π-π stacking interactions of [BMIM] [PF6] enhanced the adsorption of MB.…”
