Claim Text:
1. A structure comprising: a nitridated material, wherein the nitridated material has the characteristic of capturing CO 2 , wherein the nitridated material has a surface selected from: a nitridated silica material, a nitridated metal oxide material surface, or a nitridated non-metal oxide material, wherein the nitridated material is formed through cyclic chlorination and ammoniation of a material to densify NH 2 groups on the material surface, wherein cyclic chlorination and ammoniation includes dehydroxilation of the material followed by chlorination with thionyl chloride and ammonia adsorption and subjecting the ammoniated trichlorosilylated material to another exposure to trichlorosilylation ammoniation to form a surface having a network of surface —Si(NH) 2 —(NH)—Si—(HN 2 ) 2 or 3 .
