It is demonstrated that graphene‐based porous silica sheets can serve as an efficient carrier support for PEI via a simple nanocasting technology. The resulting materials possess thin nature, high PEI loading content and high thermal‐conductivity. Such features are favorable for the efficient diffusion and adsorption of CO 2 as well as the rapid thermal transfer during the CO 2 capture process.
