Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Layered double hydroxides (LDHs) with a hierarchical mesostructure are successfully synthesized on mesoporous silica foams by simple impregnation and hydrothermal treatment. The as‐synthesized LDH/silica foam nanocomposites show well‐defined mesostructures with high surface areas, large pore volumes, and mesopores of 6–7 nm. The nanocomposites act as carbon dioxide (CO₂) sorbents under simulated flue gas conditions. They also exhibit significantly enhanced CO₂ capacities under high‐pressure conditions and high CO₂/N₂ and CO₂/CH₄ selectivities.</p> </abstract>
