Metal-organic framework (MOF) is a promising template to synthesis highly efficient calcium-based sorbents for high temperature CO2 capture. However, the way of loading promoter on calcium oxide affects the CO2 sorption performance of MOF-derived sorbents. In this work, a series of MOF-derived sorbents with three promoter types (Al2O3, MgO, ZrO2) are synthesized from one-step synthesis method and two-step synthesis method to investigate the influence of loading strategy on the material structure and sorption behavior. Detailed characterization techniques and reaction kinetics are used to interpret the essential reason for different reactivity of the sorbents using two loading strategies. Loading strategy affects promoter loading, crystallite size, CO2 sorption capacity and sorption/desorption rate, but leads to a limited impact on reaction time. Two-step synthesis method contributes to a higher promoter loading for the sorbents, due to the absence of coordination competition between calcium and metal cations to form a bimetallic MOF template. Moreover, it is benefitted to yield higher CO2 sorption capacity and CO2 retention rate, even introduces a self-activation effect by reorganizing the material structure. The result provides a useful guide to optimize the connection way between promoter and calcium oxide for improving the sorption activity and thermal stability of CO2 sorbents.
