“…The dye elimination process follows first-order kinetics ( C 0 is small): RhB, MB, ARB, and AY17 all follow the equation where C t is the dye solution concentration at time “ t ”, C 0 is the dye solution concentration at t = 0, and k is the rate constant. The calculation formula of dye degradation efficiency is degradation efficiency (%) = [( C 0 – C t )/ C 0 ] × 100%. , …”

Two novel Co-based metal−organic frameworks, namely, [ C o 3,5biphenyltricarboxylic acid, 4,4′-tmdp = 4,4-trimethylenedipyridine, and 1,4-bimb = 1,4-bis((1H-imidazol-1-yl)methyl)benzene), were synthesized under hydrothermal conditions and characterized. In this study, by adjusting several experimental parameters including catalyst dosage, PMS volume, temperature, and the initial value of pH, PMS activation toward two cationic dyes and two anionic dye degradations was systematically examined. Radical scavenging experiments revealed that SO 4•− is considered to act as the paramount reactive oxygen species in the oxidation process. The Co(III)/Co(II) recycle of CUST-560 and CUST-561 is able to carry out an effective electronic transfer to PMS, facilitating the reaction process; thus, an eminent catalytic property has emerged. Consequently, the original material as-synthesized is thought to be a splendid activator to peroxymonosulfate activation for extermination and decolorization of dyes.

Water quality can have serious impacts on human health. One crucial issue of water pollution seriously affects our safety due to the continually emerging of discovered anthropogenic pollutants. The water treatment technologies are persistent improvement to adapt such new contaminants, which accelerates the evolution of materials science to explore solving the problems. Metal-organic Frameworks (MOFs) as the significant porous and multi-dimensional networks has been concerned for toxic pollutant elimination, especially probed the applications of outstanding layered 2D skeletons MOFs-based materials. The emphases of this review highlight the 2D MOFs-based materials used in water remediation and treatment strategies including adsorption and catalysis methods. Further, the prospects and challenges of 2D MOFs-based materials for water treatments applications would be surveyed meticulously for the future research and development.

“…Among them, degradation of organic dyes by complexes has attracted more and more attention in recent years. For instance, Das et al [ 29 ] synthesized two Co (II)‐based complexes, with excellent photocatalytic efficiency to degrade RhB and MB. Adhikary et al [ 30 ] reported a porous Zn(II)‐based complex, which can photocatalytic degradation of RhB and MB under ultraviolet illumination.…”

The complex [Cd(PDNDI)]·DMF (Cd‐PDNDI) (H2PDNDI = N‐(4‐pyridine)‐4,5‐dicarboxy‐1,8‐naphthalene dicarboxyimide) was synthesized by the reaction of N,N′‐di(4‐pyridyl)‐1,4,5,8‐naphthalene diimide (DPNDI) and Cd(NO3)2·4H2O. It was characterized by elemental analysis, infrared spectroscopy, ultraviolet–visible (UV‐vis) spectroscopy, powder X‐ray diffraction (PXRD), single crystal X‐ray diffraction, and thermogravimetric analysis. Structural analysis shows that the Cd‐PDNDI has a self‐assembled 3D network structure with the rtl type topology. It is worth mentioning that the composition of the ligand is different from the initial raw material used in this molecular structure. This may be because the ligand undergoes an in situ hydrolysis reaction in the reaction system and becomes an NDI carboxylic acid derivative, which continues to join coordination reaction with the metal ion. In addition, the Cd‐PDNDI has an excellent photocatalytic effect on malachite green (MG) among the six dyes, which shows that the Cd‐PDNDI could be used as a photocatalytic material for the degradation of dyes.
