Design and synthesis of sprayable nanocomposite coatings for carbon capture and direct conversion into environmentally safe stable carbonates

► Sprayable nanocomposite coatings for large-area carbon capture and storage. ► Combination of different functional properties of oxide nanoparticles in a polymer. ► Catalytically active localized reaction spots generated by dispersed nanoparticles. ► Increasing nanoparticle concentration results in conversion into stable carbonates.
