Abstract
A carbon dioxide-absorbing material containing lithium titanate, the lithium titanate comprising 70 mol % or more of Li4TiO4 and 30 mol % or less of Li2TiO3. Furthermore, the carbon dioxide-absorbing material is obtained by the method for producing a carbon dioxide-absorbing material described below. That is, the absorbing material is obtained by the production method which produces the same by mixing given raw materials such that the atomic ratio between lithium and titanium is from 3.5 to 5.0, and subjecting the resulting mixture to heat treatment. The method for absorbing carbon dioxide includes a carbon dioxide absorption step. The apparatus for absorbing carbon dioxide is provided with carbon dioxide absorption means that absorbs carbon dioxide in the carbon dioxide-absorbing material.
