1. A recyclable catalyst for carbon dioxide capture, comprising:
a porous metal-organic crystallite, wherein the porous metal-organic crystallite comprises a porous complex of Ba ions and units of 4,4′,4″-s-triazine-2,4,6-triyl-tribenzoic acid;
wherein walls of the pores of the porous metal-organic crystallite have a molecular honeycomb pattern formed by the porous complex, and
wherein the pores of the molecular honeycomb pattern have an average pore width of 17 to 19 Å and barium clusters active metal sites.
