“…In order to verify about the specific surface areas of the parent framework (CUT1) and its composite (CUT1@5 %AC‐Black), the nitrogen adsorption desorption studies were carried out and the specific surface areas were calculated using Brunauer‐Emmett‐Teller (BET) method. As indicated in Figure 6, the nitrogen adsorption desorption isotherms of the CUT1 and CUT1@5 %AC‐Black possesses similar reversible type‐IV adsorption desorption behavior [50–51] . The presence of hysteresis loops in both the compounds at the partial pressure range from 0.4 to 1.0 indicates that CUT1 and composite were obtained uniform pore size distribution along with a typical microporous structure in the physical mixture.…”

The development of porous tetrazolate metal‐organic frameworks (MOFs) and their carbon composites for the efficient adsorption of organic dyes is a highly exciting field for material developments as well as waste water treatment. Herein, we have introduced a copper tetrazole‐based metal organic framework, {(Cu(C2N4H3); CUT1}, synthesized via in‐situ ligand synthesis followed by [2+3] cycloaddition strategy. A set of activated carbon (AC) composites namely as CUT1@1 %AC‐Black and CUT1@5 %AC‐Black have also been prepared by loading of different proportions of activated carbon (AC) in CUT1 via sonication process. Single‐crystal X‐ray data and topological analysis results have been shown that the parent MOF (CUT1) exhibits a three‐dimensional extended structure and formed 43.62.8 ptr net topology. The phase purity and surface area of as‐synthesized MOF and AC composite have been examined through various techniques. The dye adsorption properties have been investigated for present materials by using three anionic dyes and three cationic dyes at room temperature. The results of adsorption studies demonstrated that 5 wt.% AC carbon composite is adequate for promising adsorption activity against all selected organic dyes compared to parent MOF (CUT1). A minor enhancement of surface area in the composite material exhibits the adsorption of both the cationic and anionic dyes rendering the structure and morphology remains unchanged.

“…UV‐vis spectroscopy was used to investigate the potential application of synthesized Co‐PCPs as catalysts for the degradation of anionic dyes at room temperature using 0.3 mM of the aqueous dye solution of MO/OII. These dyes are highly stable and resistant to biodegradation and exhibit maxima at 464 nm (MO) and 480 nm (OII) (Figure S2) [40,41] . For the degradation process, NaBH 4 was used in excess to enhance the reaction rate [42,43] .…”

[40,41] For the degradation process, NaBH 4 was used in excess to enhance the reaction rate. [42,43] Control experiments showed a maximum degradation efficiency of MO and OII was achieved ~13-14 % (Figure S12), whereas ~99 % of dye degradation was achieved within ~1 h using the Co-PCPs.…”

Abstract2,2’‐Bipyridine‐derived two chelating linkers containing two and three bipyridine units were synthesized and characterized. Solvothermal condensation of these linkers with Co(NO3)2.6H2O generated cobalt‐based porous coordination polymers (Co‐PCPs). The scanning electron microscopy studies revealed the macroporous nature of the Co‐PCPs, with the highest surface area achieved up to 441.1 m2 g−1. The Co‐PCPs were found to be effective catalysts in the degradation of the anionic dyes, methyl orange (MO) and orange 2 (OII), in the presence of sodium borohydride. Also, the synthesized PCPs were found to selectively catalyse the degradation of anionic dyes from a mixture of dyes (~99 % degradation in 55 min). Regeneration studies showed that the PCPs could be regenerated and reused for more than five cycles with ~98 % retention of degradation efficiency and are promising materials for the selective degradation of anionic dyes from wastewater.
