This study reports the development of shape-controlled TiO2 (B)/anatase heterostructures for degradation emerging environmental pollutants, including phenol, methomyl (insecticides), and diclofenac sodium (drug), under UV-visible-light irradiation in ultrapure water alkaline stormwater. nanobelts were synthesized via a surfactant-free hydrothermal method, yielding structures with widths ranging from 40 to 80 nm lengths extending up several micrometers. The calcined at 400 °C, 600 800 °C form heterostructure. For comparison, calcination 900 was also performed, resulting formation pure anatase. samples (~92% anatase, ~8% nanobelts) exhibited enhanced photocatalytic efficiency, achieving significant total organic carbon (TOC) removal complete mineralization both matrices. These findings contribute cost-effective method developing efficient avoid rapid charge carrier recombination, strong potential advanced wastewater treatment.

This overview provides insights into organic and metal–organic polymer (OMOP) catalysts aimed at processes carried out in the liquid phase. Various types of polymers are discussed, including vinyl (various functional poly(styrene-co-divinylbenzene) perfluorinated functionalized hydrocarbons, e.g., Nafion), condensation (polyesters, -amides, -anilines, -imides), additional (polyurethanes, polyureas, polybenzimidazoles, polyporphyrins), prepared from organometal monomers. Covalent frameworks (COFs), (MOFs), their composites represent a significant class OMOP catalysts. Following this, preparation, characterization, application dispersed metal discussed. Key catalytic such as alkylation—used large-scale applications like production alkyl-tert-butyl ether bisphenol A—as well reduction, oxidation, other reactions, highlighted. The versatile properties COFs MOFs, well-defined nanometer-scale pores, large surface areas, excellent chemisorption capabilities, make them highly promising for chemical, electrochemical, photocatalytic applications. Particular emphasis is placed on potential CO2 treatment. However, notable drawback COF- MOF-based relatively low stability both alkaline acidic environments, high cost. A special part devoted to deactivation disposal used/deactivated catalysts, emphasizing importance separating heavy metals conclusion guidance selecting developing OMOP-based

Abstract Adsorption using covalent organic frameworks (COFs) is very effective and favoured for removing per- polyfluoroalkyl substances (PFAS) from various matrices. The prominent classes of COF, their synthesis methods, application in COF-based technologies PFAS adsorption myriad environments are discussed. Furthermore, the influencing characteristics distinct COF also examined. COFs have large specific surface areas porosity, offering PFASs a host sites thus high capabilities. β -Cyclodextrin-based ( -CD-COFs), ionic (iCOFs), amine-functionalised COFs, porphyrin-based hydrophobic some most notable examples as such been employed large-scale remediation. Direct post-synthetic modification two main design methodologies. general approach constructing involves reaction ion monomers with other neutral monomers. For solvothermal currently direct synthetic method. process used to synthesise tremendously impacts how effectively they adsorb PFAS. High-performance materials remediation created by researchers customising suitable techniques. authors’ objective give readers alike broad overview current status research development, including numerous challenges prospects associated COFs.
