Abstract :

Metal-Organic Framework (MOFs) are new crystalline materials which because of having propertiessuch as high porosity, optical and electrical properties, etc., have been considered in areas such as gasstorage, catalysis, pollutants removal and so on. Therefore, in order to develop these compounds andtheir use in this study, in this work, Zn-HKUST-1 metal-organic framework was synthesized by fastand also environmentally friendly physical mixing (grinding by hand) method. To identify productsspectroscopy methods such as FT-IR and PXRD were employed. The sensing ability of this frameworkto detect explosive-like nitroaromatic analyets such as nitrobenzene, 1,3-dinitrobenzene and TNT wastested. The results showed that the sensitivity of Zn-HKUST-1 to TNT is more than two other analytesand this metal-organic framework can be effective in detecting explosives such as TNT. Alsoultrasound assisted synthesis (sonochemical) of this framework and effect of initial reagentsconcentration and power generating ultrasonic apparatus on the size and shape of the products wereinvestigated.
