Abstract: The present invention relates to a method for continuous removal of carbon dioxide, the method comprising the steps of: a) preparing an aqueous solution containing an amine-based compound and an acidic calcium compound; b) bringing a gas containing carbon dioxide to be treated into contact with the aqueous solution to prepare a calcium carbonate precipitate; and c) recovering the calcium carbonate and then adding a basic calcium compound to the residual aqueous solution, wherein after step c), step b) and step c) are repeatedly performed. The removal of carbon dioxide by the method of the present invention has advantages of requiring low energy and being capable of mineralizing and removing carbon dioxide at a fast rate without a separate time for induction.

Abstract: A single atom catalyst for carbon dioxide conversion which allows mass production at low cost without performing a pretreatment of a carbon support and a post-treatment of a final synthesized catalyst is prepared. The single atom catalyst for carbon dioxide conversion was confirmed to have a low metal content to reduce production costs, and to have high carbon monoxide selectivity, carbon monoxide production rate, and stability.
