Polyhedral oligomeric silsesquioxane functionalized with imidazolium chloride peripheries was synthesized and successfully used as a catalyst for CO ₂ conversion.

Single walled carbon nanotubes were functionalized with imidazolium based salts and successfully used as catalysts for the conversion of CO₂. The novel materials displayed excellent catalytic activity.

Imidazolium-based silica microreactors were synthesized through self-organization/polymerization of the amphipathic organic salts that behave as templates for the construction of silica architecture and as catalytic active sites. The organic–inorganic hybrid microreactors displayed excellent catalytic performance in the conversion of CO₂.
