Synthesis, Structure and Topology of Copper(I) Tetrazolate Framework: Facile Approach to Design Multiple Dye Adsorbent with Carbon Composites

Abstract

AbstractThe 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.
