Cu- organic framework modified by diatomite: synthesis, characterization and antimicrobial studies

This work is concerned with the studies of the bioactivities of the prepared Cu-MOF compound and its modification with diatomite. This work aims to preparation and characterization of Cu-MOF nano-particles and evaluation against some organisms. Otherwise, the structure of the Cu-MOF was modified and the effects of modification on the bioactivity were investigated. Cu-MOF/diatomite was prepared and their characterizations by using different methods were carried out. The characterization by flourier transforms Infrared red (FTIR), X-ray diffraction (XRD), transmission electron microscope (TEM) and thermal degradation analysis (TGA) indicates that Cu-MOF incorporated onto the diatomite unit. The thermo-gravimetric studies showed that as the diatomite particles coated with the organic fragments prevent their thermal decomposition at low temperature. The bioactivity of Cu-MOF/diatomite was studied by using the agar diffusion technique; it is found that incorporated Cu-MOF onto diatomite increases the bioactivity of Cu-MOF.
