Abstract
A material is fabricated for capturing CO2 at mid-high temperature. The material is a layered material containing Ca, Al carbonates. A higher ratio of Ca to Al helps capturing CO2. The temperature for capturing CO2 is around 600° C. The material can even release CO2 at a high temperature. Thus, the material can process looping cycles of carbonation and decarbonization at a CO2 carbonation scale of 45% gCO2/g.
