Carbon dioxide sensor material and device based on ion conduction gain effect

The invention provides a carbon dioxide sensor material and device based on an ion conduction gain effect. The carbon dioxide sensing material comprises a metal organic framework and an ionic conduction enhanced object, and the ionic conduction enhanced object is encapsulated on the metal organic framework; the metal organic framework is at least one of alpha-cyclodextrin-MOF (Metal Organic Framework), beta-cyclodextrin-MOF (Metal Organic Framework) and gamma-cyclodextrin-MOF; the ionic conduction enhanced guest comprises xanthene dye containing one or more carboxyl groups, hydroxyl groups, sulfonate radicals and first-stage to third-stage amino groups. The metal organic framework body has extremely high carbon dioxide adsorption capacity, oxygen-containing groups such as carboxyl and sulfonate radicals on guest molecules can form a hydrogen bond network with the metal organic framework body, ion conduction is facilitated, and the detection effect of the material on carbon dioxide is greatly improved; the met
