Crystallized glass tailored by controlled heat treatment for carbon dioxide capture under mild conditions

Described is the formation of crystallized alkaline earth oxide-containing glass adsorbents for radioactive carbon dioxide ((CO2)-C-14) sequestering and mineralization under mild operating conditions; thus enabling the long-term geological disposal of hazardous C-14. The best performing crystallized glass adsorbents recorded a max CO2 capacity of 4.54 mmol g(-1) and a carbonation reaction rate of 8.04 mmol g(-1) h(-1).
