Abstract

A simple and green synthesis protocol has been employed to get Ca-ada (calcium-adamantanecarboxylate), the precursor to a hybrid organic-inorganic composite material for high temperature CO₂ capture applications. The resultant hybrid material shows near 100 percent carbonation at high temperature. It shows excellent CO₂ cycling performance under flue gas conditions (14% CO₂) and retains close to 94.4% of its initial capture capacity after 10 cycles. The cycling behaviour of the sample was also tested under harsh regeneration conditions (80% CO₂, 920 °C). The resultant hybrid out performs CaO derived from Ca(OH)₂ and limestone both in terms of CO₂ capture and cycling performance.
