CO <sub>2</sub> Fixation and Release Mediated by Carbonate-Based Coordination Polymers

We demonstrate the synthesis of 11 carbonate (CO<sub>3</sub><sup>2-</sup>)-based coordination polymers (CPs) from CO<sub>2</sub> and reveal the structure-property correlation of CO<sub>2</sub> release upon decarbonation. The decarbonation temperatures (<i>T</i><sub>CO2</sub>) are tunable as factors of the electronegativity of metal ions and the coordination numbers of CO<sub>3</sub><sup>2-</sup> within the CP lattices. The structural tunability of CO<sub>3</sub><sup>2-</sup>-based CPs enables high gravimetric CO<sub>2</sub> contents (25-30 wt %) and <i>T</i><sub>CO2</sub> in the low-temperature range where low-grade waste heat can be utilized (170-230 °C). The decarbonation mechanism of CO<sub>3</sub><sup>2-</sup>-based CPs, which produces a discrete metal complex, is revealed by 3D electron diffraction and variable-temperature synchrotron X-ray diffraction.

Abstract

We demonstrate the synthesis of 11 carbonate (CO<sub>3</sub><sup>2-</sup>)-based coordination polymers (CPs) from CO<sub>2</sub> and reveal the structure-property correlation of CO<sub>2</sub> release upon decarbonation. The decarbonation temperatures (<i>T</i><sub>CO2</sub>) are tunable as factors of the electronegativity of metal ions and the coordination numbers of CO<sub>3</sub><sup>2-</sup> within the CP lattices. The structural tunability of CO<sub>3</sub><sup>2-</sup>-based CPs enables high gravimetric CO<sub>2</sub> contents (25-30 wt %) and <i>T</i><sub>CO2</sub> in the low-temperature range where low-grade waste heat can be utilized (170-230 °C). The decarbonation mechanism of CO<sub>3</sub><sup>2-</sup>-based CPs, which produces a discrete metal complex, is revealed by 3D electron diffraction and variable-temperature synchrotron X-ray diffraction.
