“…The bond distance of Cu−N is in the range of 2.042(4) to 2.055(3) Å (av. Cu−N=2.048 Å) that are closely comparable to the earlier reported literature of copper tetrazolate framework structure [48] . The ∠N−Cu−N bond angles vary from 96.81(13)° to 118.6(2)° with the average of 107.71° confirming the tetrahedral geometry of each copper center (see the ESI, Table S1).…”

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.

“…Increasing the electrostatic interaction between the dye molecules and adsorbent material desired the process may either endothermic or exothermic. The adsorption reaction was carried out under room temperature with good adsorption percentage; it was proved that the adsorption of CR and MG in CA‐Fe 3 O 4 @ZnO is an exothermic process [56, 57] …”

Cellulose acetate polymer membrane was fabricated with Fe3O4@ZnO core‐shell nanoparticles through phase inversion technique to enhance the hydrophilic &antifouling properties. The morphology, crystallinity, porosity and surface area of the core shell nanoparticles incorporated membrane were examined using X‐Ray Diffraction (XRD), Fourier‐transform infrared spectroscopy (FT‐IR), High‐resolution scanning electron microscopy (HR‐SEM), High‐resolution transmission electron microscopy (HR‐TEM) /Energy Dispersive X‐ray analysis (EDX) studies. The contact angle measurement and wettability test prove the improvement of the hydrophilicity of the membrane with the addition of nanocomposite materials. Adsorption test were performed with the of model dyes such as Congo red (Anionic dye) and Malachite Green (Cationic dye) were investigated using Ultraviolet‐visible spectroscopy. The adsorption percentage against Congo Red (CR) and for Malachite green (MG) were found to be 93 % and 70 % respectively. Kinetic studies exhibits the rate of the reaction, for CR dye it shows R2=0.9471 and R2=0.8609 for MG dye, which obeys the pseudo first order reaction. In addition, the adsorption isotherm model as Langmuir shows that KI values are 0.00338(L/mg) and 0.0486(L/mg) respectively. Desorption studies exhibits the maximum desorption of dye for Congo red is 89 % and 83 % for Malachite Green.In a recyclability process, membrane material adsorbs 90 % of Congo red dye and 63 % of Malachite green dye.

“…Recently, M. Shahid et al, reported a porous metal organic framework, [Cu(Metet)] n (MOF-1), which was synthesized via a solvothermal method employing NaN 3 and 2-amino-4-picoline. 125 The porous MOF, which was formed in situ during the autoclave, reaction showed a tremendous adsorption performance towards methylene blue dye. The adsorption process was carried by adsorbing the dye into the pores of MOF-1, as shown in Fig.…”
