Prediction of phase transitions by investigating CO2 adsorption on 1% lithium doped MIL-101 (Cr) MOF with anomalous type isosteric heat of adsorption.

Some data are reported for the regions below the triple point (200 K–216.5 K). The multilayer CO2 adsorption uptakes in a series of discontinuous jump are found in the sub-triple region. Various types and shapes of Qst are observed and the unexpected differences in Qst at sub-triple, sub-critical and super critical regions are explained. At sub-triple zone, two sharp spikes of Qst against uptakes are found for identifying the transitions of adsorbate layer from the gaseous phase to the solid phase. The gas – liquid transition is also observed from the uptake dependence Qst data at 220 K and 240 K. A monotonic decrease in Qst is found at higher temperatures.||URI:||https://hdl.handle.net/10356/85816
