- Abstract
The molar heat capacities of one-three-dimensional zeolitic imidazolate frameworks Zn(C4H6N2)2 (ZIF-8) were measured by temperature-modulated differential scanning calorimetry over the temperature range from 213 to 423 K for the first time. No phase transition or thermal anomaly was observed in the experimental temperature range. The fundamental thermodynamic parameters such as entropy and enthalpy relative to 298.15 K were calculated based on the experimentally determined molar heat capacities. The compound was characterized by powder XRD and FT-IR spectroscopy. Moreover, the thermal decomposition characteristics of ZIF-8 were investigated by thermogravimetry spectrometer (TG).
