Abstract
A solid recovery material for carbon dioxide includes from 1% by weight to 99% by weight of sodium ferrite and from 1% by weight to 99% by weight of porous material. The material has an average particle diameter of 1 mm to 10 mm, and having a specific surface area of 5 m/g to 1500 m/g. An axial ratio of an average major axis diameter to an average minor axis diameter of primary particles of the sodium ferrite is from 1 to 2.
