摘要: As a common precursor for supercritical CO2 (scCO2) deposition techniques, solubility data of organometallic complexes in scCO2 is crucial for the preparation of nanocomposites. Recently, metal acetylacetonates have shown great potential for the preparation of single-atom catalytic materials. In this study, the solubilities of iron(III) acetylacetonate (Fe(acac)3) and nickel(II) acetylacetonate (Ni(acac)2) were measured at the temperature from 313.15 to 333.15 K and in the pressure range of 9.5-25.2 MPa to accumulate new solubility data. Solubility was measured using a static weight loss method. The semi-empirical models proposed by Chrastil and Sung et al. were used to correlate the solubility data of Fe(acac)3 and Ni(acac)2. The equations obtained can be used to predict the solubility of the same system in the experimental range.
