synthesis of new nanocomposite based on metal-organic framework montmorillonite consists of cu2o and investigation of its antibacterial properties

One of the metal-organic framework (mof) materials called mof-2 with the formula [zn2(bdc)2] has attracted the attention of researchers. here, we describe the preparation and synthesis of high-quality mof-2 in more stable and simple conditions such as room temperature [1]. on the other hand, montmorillonite (mmt), a nano layered clay mineral that combines with this metal-organic framework to form a new environmentally friendly clay-based composite mof-2/mmt using an in-situ growth technique created [2]. the synthesized composite modified by cu2o nanoparticles and new prepared nanocomposite (mof-2/cu2o/mmt) was used for antibacterial tests. cu2o nanoparticles were used in composite in order to increment of antibacterial activity. the results show that the nanocomposite has been synthesized correctly and completely. the results showed mof-2 were synthesized in the interlamellar space of mmt. cu2o nanoparticles were incorporated in composite by the simple green method. cuso4 salt and nettle leaf extract were used as a copper precursor and reducing agent, respectively [3].the results of antibacterial testing of these compounds have also been announced. the antibacterial activity of mof-2 and the mentioned composites was tested against gram-positive and gram-negative bacteria. the mof-2, mof-2/mmt and mof-2/cu2o/mmt showed efficient antibacterial activity. antibacterial activity can be related to release of cations from synthesized compounds such as cu2+, zn2+.
