Fabrication of Silver-Doped UiO-66-NH2 and Characterization of Antibacterial Materials

Metal-organic frameworks (MOFs) are highly crystalline inorganic-organic complexes formed from metal ions or clusters and multi-toothed organic ligands. MOFs have great potential for use in antibacterial materials the biological, environmental, food antimicrobial fields. They can act as a reservoir of ions, releasing them gradually leading to sustained effect analogous that proposed oxide nanoparticles (NPs). Herein, UiO-66-NH2 type MOF was first prepared by facile solvothermal method then loaded with Ag NPs form Ag/UiO-66-NH2 composite different were synthesized controlling silver doping amount, which applied an test. Works on synthesis its test not reported before. The characterized using field emission scanning electron microscope (FE-SEM), X-ray diffractometer (XRD), Fourier transform infrared spectroscopy (FT-IR), Brunauer-Emmett-Teller (BET), thermal gravimetric analysis (TGA), photoelectron (XPS) techniques. activity assessed against E. coli (gram-negative bacteria) Staphylococcus aureus (gram-positive bacteria), inhibition zone (ZIO) optical density (OD) method. obtained results shown introduction does interfere crystallization UiO-66-NH2. FT-IR spectral profiles recorded samples fabricated under conditions varying ion levels similar those stability containing amounts lower than However, these conditions, specific surface area pore volume increased. performance improved significantly following process doping. best observed when content 4 wt.%. Overall, we new nanocomposite material broad-spectrum bacterial sterilization, easy manufacture.
