Dye encapsulated ZIFs materials were reported for CO2 adsorption. Dye molecules enhanced the adsorption capacity of CO2 . Dye@ZIF-8 showed a superior capacity for CO2 of 1.46 mmol•g -1 at 273 K. It provided a 42 % higher adsorption capacity than that of ZIF-8 (0.84 mmol•g - 1 ) under the same conditions . The guest molecules such as dyes improved the adsorption capacity of CO2.
