Abstract: The use of low-cost and easily accessible fly ash for CO2 mineralization and sequestration can effectively control carbon emissions. In this paper, Mg(OH)2 was used as a reaction catalyst, and ultraviolet radiation was applied to fly ash to enhance its CO2 uptake capacity. The effects of temperature, catalyst content, and UV radiation time on the CO2 uptake performance of fly ash under low-concentration CO2 conditions were studied respectively. The experimental results show that UV radiation can effectively promote the CO2 uptake capacity of modified fly ash. After adding 0.5 g of Mg(OH)2 and 24 h UV radiation pretreatment, the CO2 uptake capacity of fly ash reaches 70.77 g-CO2/kg-FA, and the carbonation efficiency is 58.31%.
