“…As a result, the rational design of CPs with coordination unsaturated metal ions is significant and intriguing. [47] Zhai et al, were inspired by this concept and thus developed a new coordination unsaturated Cu(II) CPs, denoted as {[Cu-(tptc)0.5(bimb)] • 2H 2 O • 0.5NMP}n (1). This CPs was constructed using p-terphenyl-2,2'',5'',5'''-tetracarboxylate acid (H4tptc) and 1,3-bis(imidazol-1-ylmethyl)benzene (bimb).…”

To address global pollution caused by contaminants in water bodies, it is crucial to develop an efficient and environmentally friendly treatment process for wastewater from various industries. Advanced oxidation processes (AOPs) have proven to be highly effective in wastewater treatment due to their high oxidation efficacy and the absence of secondary pollutants. Different methods such as ozone, Fenton, electrochemical, photolysis, and sonolysis can be used in AOPs to degrade emerging pollutants that are resistant to conventional methods. In recent years, nanotechnology has emerged as a viable solution, with various nanomaterials being developed for wastewater treatment. Among them, copper‐based nanocatalysts have shown great potential in AOPs. This review focuses on the progress and mechanisms of copper‐based nanocatalysts in wastewater treatment via AOPs. It also discusses the challenges associated with oxidation, electrochemistry, Fenton, and photocatalysis in wastewater treatment processes.

“…Nitrophenols are widely employed as raw materials or intermediates for the synthesis of dyes, rubber additives, medicine, photosensitive materials, and other fine chemicals. , Therefore, they inevitably exist in the industrial wastewater of the above processes, causing serious pollution to water resources. Nitrophenols can directly damage or mutate DNA and cause possible cancer in the human body due to their high toxicity, especially o- nitrophenol (ONP), which is harmful by inhalation, in contact with skin, and if it is swallowed, and hence it is listed as one of the priority pollutants. , Consequently, it is greatly significant to explore effective methods for the removal of nitrophenols from wastewater.…”

“…For example, Zhang et al employed imidazolyl dicationic ionic liquid as the monomer and constructed a nitrogen-rich polymer for the adsorption of p- nitrophenol (PNP) from aqueous solution and its equilibrium capacity reached 437 mg/g at 298 K. Cheng et al synthesized two-dimensional (2D) covalent organic frameworks (COFs) and it was proven efficient for the adsorption of 2,4,6-trinitrophenol (TNP) with the maximum capacity ( q max ) of 1045 mg/g according to the Langmuir model. Hou et al applied the amino-rich coordination polymer Cu 2 I 2 (MA) 2 for the adsorption of PNP and TNP from water, and their q max at 293 K were up to 285 and 131 mg/g, respectively.…”

Herein, three multiple phenolic hydroxyl aromatic compounds, namely, p-dihydroxybenzene (PD), 1,3,5-trihydroxybenzene (TB), and gallic acid (GA), were applied as the chemical modifiers and incorporated into initial polymers via nucleophilic substitution, hence creating intermediates with different phenolic hydroxyls (−OH). Thereafter, Friedel−Crafts alkylation resulted in multiple phenolic −OH-modified hyper-cross-linked polymers (HCPs), namely, PS−PD-DCE, PS-TB-DCE, and PS-GA-DCE. The final polymers exhibited a high Brunauer−Emmett−Teller (BET) surface area (S BET : 504−573 m 2 /g), large pore volume (V total : 0.48−0.54 cm 3 /g), and plentiful phenolic −OH (acidic exchange capacity: 1.2−2.6 mmol/g). The adsorption experiments revealed that PS-GA-DCE with the highest phenolic −OH was the most efficient adsorbent for the adsorption of o-nitrophenol from aqueous solutions, and the predicted maximum capacity (q max ) at 298 K was 1052 mg/g according to the Langmuir model, surpassing the data of most synthetic adsorbents in previous studies. The micropore diffusion model and the intraparticle diffusion model effectively elucidated the kinetic data. 5% of sodium hydroxide desorbed o-nitrophenol from the polymers completely, and the equilibrium capacity dropped to 85.5% after five repeated adsorption−desorption cycles. The adsorption mechanism revealed that hydrogen bonding was primarily responsible for the adsorption, with micropore filling serving as an additional contributing factor. These results provide valuable insights into the synthesis and application of chemically modified polymers for the enhanced adsorption performance.

A novel zinc‐based metal–organic framework (Zn‐MOF), designated as [Zn3(L)(bpyp)2(HCOO)3·2DMF·H2O] (1), was synthesized using 2,5‐bis(pyrid‐4‐yl)pyridine (bpyp), 1,3,5‐benzenetricarboxylic acid (H3L), and Zn(CH3COO)2·2H2O in a DMF solution. Single‐crystal X‐ray diffraction analysis revealed that MOF 1 crystallizes in the monoclinic system with a C2/c space group, featuring a (3,5)‐connected binodal network. The structural integrity and characteristics of MOF 1 were confirmed by Fourier transform infrared (FT‐IR), thermal gravimetric analysis (TGA), powder X‐ray diffraction (PXRD), and Brunauer–Emmett–Teller (BET) analyses, showing type IV isotherms indicative of microporous structures. The photocatalytic efficiency of MOF 1 was evaluated for the degradation of various antibiotics under UV light, with nitrofurantoin (NFT) demonstrating the highest degradation rate of 83.9% at an optimal concentration of 40 ppm and catalyst loading of 5 mg. The degradation process followed a pseudo‐first‐order kinetic model with a rate constant of 0.02492 min−1. Radical trapping experiments identified superoxide radicals (O2˙−) and holes (h+) as the predominant reactive species, while hydroxyl radicals (˙OH) played a negligible role. Reusability tests over four cycles confirmed the stability and durability of MOF 1, with consistent photocatalytic performance and unchanged structural morphology as evidenced by PXRD and SEM analyses. The proposed mechanism involves photoinduced electron–hole pair generation, with subsequent formation of reactive oxygen species (ROS) facilitating NFT degradation. This study highlights MOF 1 as a promising photocatalyst for environmental remediation, specifically for the efficient degradation of pharmaceutical contaminants in aquatic systems, providing insights into its structural properties, photocatalytic activity, and underlying degradation mechanisms.
