| description | The present invention relates to a method for preparing a catalyst for decomposing carbon dioxide, a catalyst for decomposing carbon dioxide prepared thereby, and a method and apparatus for decomposing carbon dioxide using the same. The catalyst for decomposing carbon dioxide according to an embodiment of the present invention has a deficiency of oxygen atom through the reduction of a metal oxide, and thus can decompose carbon dioxide efficiently. In addition, the catalyst for decomposing carbon dioxide can be obtained with no chemical binding process, such as heat treatment, through an impregnation process by adding rhodium, and the low-temperature activity of the metal oxide catalyst is increased due to a hydrogen (H_2) spillover phenomenon, thereby providing a catalyst for decomposing carbon dioxide, including an improved activated metal oxide for decomposing carbon dioxide efficiently at low temperature.
본 발명은 이산화탄소 분해용 촉매의 제조방법, 이에 따라 제조된 이산화탄소 분해용 촉매 및 이를 활용한 이산화탄소의 분해 방법과 분해 장치에 관한 것이다. 본 발명의 일 측면에 따른 상기 이산화탄소 분해용 촉매는 금속산화물의 환원과정을 통해 산소 원자의 결손을 가지게 되므로, 효율적으로 이산화탄소를 분해할 수 있다. 또한, 상기 이산화탄소 분해용 촉매는 로듐을 첨가하여 함침법(impregnation)을 통해 열처리와 같은 화학적 결합과정 없이 얻을 수 있고, 수소 유출(H2 spillover) 현상으로 인해 금속산화물 촉매의 저온 활성도가 높아지고, 이를 통해 낮은 온도에서 효율적인 이산화탄소 분해를 위한 개선된 활성화 금속산화물을 포함하는 이산화탄소 분해용 촉매를 제공할 수 있다. |
