“…Metal–organic framework (MOF) materials are self-assembled skeleton compounds with periodic network structures from ligands and metal ions, which, thanks to their unique advantages, such as their porosity, large particular area of surface, and plenty of active functional groups, have garnered a lot of interest. − On the other hand, MOFs are modified by pyrolysis and doping, and MOF-derived materials are prepared and applied in the fields of environmental remediation, catalysts, and energy storage devices, such as batteries and supercapacitors, thus inheriting the original excellent properties of MOF . However, as far as we are aware, fewer studies have been conducted on the synergistic effect of dark light by using MOFs or MOF-derived materials.…”

Metal−organic frameworks (MOFs) are self-assembled constitutive precursors and efficient self-sacrificial templates with metal ions/clusters and organic linkers from which multifunctional materials with carbon nanostructures can be derived. In this study, we synthesized a novel Cu-MOF with Cu(II) as the central metal ion through two ligands, N,N′-bis(pyridin-3-yl)terephthalamide (3bpta) and fumaric acid (H 2 FA), which was used as a template for derivatizing carbon-based nanostructured materials of Cu and Cu x O through doping with different materials (melamine, urea, and TiO 2 ) in a simple and efficient one-step pyrolysis. The Cu/Cu x O-1 catalyst possesses both dark-catalyzed degradation activity and photocatalytic reduction activity during water purification due to the hole-transfer ability between Cu + and Cu 2+ and its inhibition of electron−hole complexation. In the absence of light, force, and cocatalyst, it can also effectively remove azo dyes in water and effectively reduce Cr(VI) under the action of visible light; therefore, Cu/Cu x O-1 can be used as a new type of bifunctional material for the removal of pollutants in water, which has a broad prospect.

“…The use of MOF as the precursor helps in the structural modulation of the MN x @NC catalysts as well as controls the morphology, porosity, specific surface area, etc. [22][23][24][25] Inspired by the above reports, we have designed a CoN x @NC catalyst for the degradation of antibiotics ciprofloxacin (CIP), amoxicillin (AMX), and dye methylene blue (MB). CIP is one of the most commonly prescribed broad-spectrum antibiotics.…”

Advanced oxidation process using reactive oxygen species (ROS) can be efficiently utilized to remove soluble contaminants from water. Herein, we have reported a facile method for the activation of molecular oxygen to produce ROS using Prussian blue analog (PBA)‐derived catalyst CoNx@NC. The two‐electron reduction of O2 by CoNx@NC produces H2O2, which is further dissociated into ⋅OH radicals and decomposes water‐soluble organic dye (methylene blue) and antibiotics (ciprofloxacin and amoxicillin). CoNx@NC is capable of removing 98 % of ciprofloxacin in a short period of time (65 minutes) in the presence of oxygen. Further, CoNx@NC can activate peroxodisulfate in the aqueous medium to produce ROS (SO4⋅−, and ⋅OH) and catalyzes the decomposition of the antibiotics and organic dye. The efficiency of the degradation of antibiotics and dye is improved when peroxodisulfate is used for the formation ROS. The higher oxidation potential and longer life‐time of SO4⋅− than ⋅OH improves the rate oxidation with peroxodisulfate. The Co−N coordination in CoNx@NC stabilizes the system against leaching and shows excellent stability for recycling (for five cycles) during the removal of contaminants.
