Due to the accelerating growth of civilian and industrial regime, chemical and bioremediation of water body become a major concern for society. Here, we report a facile and scalable process to get Zinc‐aluminium layered double hydroxide (LDH) with carbonate interlayer anion and present it as promising multifunctional material for potential applications in adsorption, antibacterial, and cytotoxicity performances. In this study, the sample was prepared by co‐precipitation method and the well crystalline LDH was characterized by Scanning Electron Microscopy (SEM), Transmission Electron Microscope (TEM), X‐Ray Diffraction (XRD), X‐Ray Photoelectron Spectroscopy (XPS) and Brunauer–Emmett–Teller (BET) analysis. The study shows excellent adsorption capacity of Zn 2 Al‐CO 3 LDH as high as 81.4 mg/g against the methyl orange (MO) dye taken as a model organic pollutant. Adsorption kinetics and adsorption isotherms have also been investigated in detail. Moreover, the prepared Zn 2 Al‐CO 3 LDH sample shows commendable antimicrobial efficacy against both Gram‐negative and Gram‐positive bacteria. In addition to that, under cytotoxicity study, the sample exhibits a creditable inhibitory effect towards the cancerous cell HEPG2 cell. As a whole the results show the significant implication of the Zn 2 Al‐CO 3 LDHas a multifunctional material towards environmental concern and also as an antimicrobial material.
