Abstract

Zeolitic imidazolate framework (ZIF) is a new class of metal organic framework (MOF) with imidazolate ligands as linkers and metal ions as metal centers. A bismuth zeolitic imidazolate framework (Bi-ZIF) was prepared by laser ablation in liquid environment as a physical bottom-up method for the first time. The samples were characterized by Fourier transform infrared (FTIR) spectroscopy for evaluation of functional groups, X-ray diffraction (XRD) for determination of crystal structure, field emission scanning electron microscope (FESEM), and transmission electron microscope (TEM) for investigation of morphology and size of produced nanostructures. The antibacterial activity of samples was investigated by Escherichia coli (E. coli) as gram-negative bacterium and Staphylococcus aureus (S. aureus) as gram-positive bacterium. Based on the results, laser ablation is a quick, capable, clean, and simple candidate method for synthesizing different kinds of ZIF.
