Title: Highly porous CO 2 hydrate generation aided by silica nanoparticles for potential secure storage of CO 2 and desalination

Abstract

Here in this paper, we report a new way of storing CO 2 in a highly porous hydrate structure, stabilized by silica nanoparticles (NPs). Such a porous CO 2 hydrate structure was generated either by cooling down NP-stabilized CO 2-in-seawater foams, or by gently mixing CO 2 and seawater that contains silica NPs under CO 2 hydrate-generating conditions. With the highly porous structure, enhanced desalination was also achievable when the partial meltdown of CO 2 hydrate was allowed.
