Abstract

Nanometer-sized ZIF-90 has been preparatied from zinc acetate dihydrate with high yield. XRD, F-TIR, SEM, TEM, BET, DTA methods were used to characterize the research samples. The results have shown that the formed ZIF-90 has crystallinity of 100 %, BET specific surface reaches 1,051 m²/g, of which the external surface reaches 292 m²/g, total capillary volume reaches 0.472 cm³/g, average crystal size of 38 nm (according to SEM), heat stable up to 285 ^oC and efficiency of 78.2 %.
