METHOD FOR PRODUCING A CATALYST FOR DECOMPOSING CARBON DIOXIDE AND A CATALYST FOR DECOMPOSING CARBON DIOXIDE PREPARED THEREBY

摘要

The present invention relates to a method for preparing a catalyst for decomposing carbon dioxide, a catalyst for decomposing carbon dioxide prepared thereby, a method for decomposing carbon dioxide using the same, and a decomposition apparatus using the same. Since the catalyst for decomposing carbon dioxide according to an aspect of the present invention has an oxygen atom vacancy through the reduction process of the metal oxide, it is possible to efficiently decompose carbon dioxide. Further, the carbon dioxide decomposition catalyst may be also added to the rhodium through impregnation (impregnation) obtained without chemical bonding process such as heat treatment, due to the hydrogen outlet (H 2 spillover) phenomenon increases the low-temperature activity of the metal oxide catalyst, this Through this, it is possible to provide a catalyst for decomposition of carbon dioxide including an improved activated metal oxide for efficient decomposition of carbon dioxide at a low temperature.
