Porous coordination polymers, called metal-organic frameworks, have attracted considerable attention due to high volume of pore, regular pore framework with uniform size, high surface area, simultaneous presence of organic and inorganic groups, and it have the wide application. In this research, metal-organic frameworks based on zinc metal Zn2bdc2dabcon were synthesized by solution at room temperature and solvothermal at 90 °C and then zinc oxide nanoparticles ZnO were dissolved by thermal degradation and removal of organic section. The samples were investigated by Fourier transform infrared FTIR for investigation functional groups, X-ray diffraction XRD for determination of crystalline structure, scanning electron microscopy SEM for studding of size and morphology, X-ray diffusion spectroscopy EDS for investigation of chemical composition, and Diffuse reflection spectroscopy DRS for determination of ultraviolet radiation absorption. Antibacterial activity of zinc oxide nanoparticles was evaluated against Escherichia coli E. coli. The results indicated that thermal degradation of metal-organic frameworks based on zinc metal can be used successfully to preparation of zinc oxide nanoparticles and final nanoparticles have an appropriate antibacterial activity against E. coli and UV-blocking, and can have a good potential for different applications.
