“…Therefore, effective utilization or conversion of CFA into a valuable product is necessary. This fly ash can be converted into porous materials, such as zeolite, and currently, zeolite has a growing market value of 1 million tons/year. , Considering this material’s valorization principle, Islam et al recently synthesized a porous network structure of zeolite from CFA for metal sorption. Because of its honeycomb-like structure and high cation exchange capacity (CEC), synthesized zeolite can be a promising candidate for CO 2 sorption.…”

This study explores an effective synthesis of zeolite Na P1 (SynZ) from coal fly ash (CFA) to capture carbon dioxide (CO 2 ) and subsequent utilization for potential fire retardation and methylene blue (MB) removal. Compared to raw CFA, SynZ exhibited extensively improved physicochemical properties, including a high surface area (94 m 2 /g), cation exchange capacity (447 cmol(+)/kg), and functionalities (Na + , −O, −OH, and −Si−O−Al−O−Si−) within its pore architecture. These properties synergistically expedited CO 2 sorption, leading to a 30-fold higher CO 2 sorption capacity using SynZ compared to CFA. However, sorption was temperature-and pressure-dependent, with 45 °C contributing to higher sorption (151 mg/g) than other studied temperatures (<95.5 mg/g). Isosteric heat, regeneration, and kinetics of sorption also proved that low-pressure conditions had a role in chemisorption and high-pressure conditions for physisorption. SynZ with captured CO 2 (SynZCO 2 ) showed excellent fire retardation behavior by preserving over 81% char residue, which is nearly 10% more than that for raw SynZ. The activation of Na 2 CO 3 and/or NaHCO 3 in the spent material could be antiflammable. Furthermore, SynZCO 2 exhibited higher MB removal (85%) than SynZ (78%), potentially as a result of a strong carbonate (HCO 3 − /CO 3 2−)-to-dye (MB + ) interaction in SynZCO 2 _MB. This research finding underscores the utilization of industrial solid waste in sustainable applications.
