Network structure-based decorated CPA@CuO hybrid nanocomposite for methyl orange environmental remediation

“…Methyl orange (MO) is one of the azo dyes that are often used as textile dyes and have different structure which depends on the acidity. Non-biodegradable methyl orange can produce several environmental pollution problems by releasing toxic and carcinogenic compounds in the waters even at low concentrations and results in induced lesions and cancers 4 . MO also famous are used in manufacturing and production of printing paper, and act as pH-indicator that convert its colour while protonated is another well-known hydrophobic anion.…”

A zinc-based coordination polymer as adsorbent for removal of trichlorophenol from aqueous solution: Synthesis, sorption and DFT studies

“…Different 5-functionalized isophthalate ligands were used alongside 4,4'bipyridyl (bpy) and Zn(II) salt, for the synthesis of four CPs, the influence of the different functionalities on the structure of the CPs was investigated [12]. Most recently, we reported two Zn(II) coordination polymers constructed with 4-nitrobenzoate/ 4-biphenylcarboxylate and 4,4'trimethylenedipyridine [13].…”

Synthesis, structural and DFT investigation of Zn(nba)2(meim)2 for adsorptive removal of eosin yellow dye from aqueous solution

“…[11][12][13][14][15][16][17][18][19][20] Apart from the adsorptive removal of dyes, they have been used as photocatalysts for the remediation of pollutants [21] .Our group previously reported the adsorption of fluorescein dye using a copper-isonicotinate metal-organic framework [22] and also the use of Zn(II) coordination polymers for the adsorption of methyl orange dye. [23] A well explored class of ligands for the synthesis of coordination compounds are the carboxylates due to their versatile complexing behaviour toward a wide range of metal ions. Benzene carboxylic acids have been particularly a good choice due to the feasibility of incorporating additional groups on the ring to provide useful properties and interactions for desired applications.…”
