Abstract

Sr ferrites with various compositions were applied to the decomposition of $CO_2$ to mitigate the greenhouse effect. In the reduction reaction of Sr ferrites up to 80$0^{\circ}C$, starting temperature was lower with increasing of Sr content in Sr ferrite. However, the reactivity was higher with decreasing Sr content. In the $CO_2$ decomposition reaction with reduced Sr ferrites, the amount of CO and C were depended on the ratio of Sr and Fe in Sr ferrite. With increasing Sr content. larger amount of C were deposited on the surface of ferrite. Therefore, in order to apply Sr ferrites for the decomposition of $CO_2$, it is necessary to control the ratio of Sr and Fe according to the conditions used.

지구온난화의 주요원인인 $CO_2$의 분해를 위해 다양한 조성의 Sr 페라이트를 이용하여 $CO_2$분해능을 비교하였다. Sr 페라이트를 80$0^{\circ}C$까지 환원시킨 결과, Sr 페라이트 내 Sr 함량이 감소할수록 높은 온도에서 환원반응이 시작되었지만, 온도가 증가함에 따라 그 환원반응성은 높아졌다. 환원된 Sr 페라이트를 이용한 $CO_2$분해 반응에서는 Sr:Fe 조성비에 따라CO나 C의 생성량이 달라졌다. 이 반응에서 Sr 페라이트 내 Sr의 비율이 감소할수록 CO의 생성량은 증가하였으며, Sr의 비율이 증가할수록 페라이트 표면에 많은 양의 C가 흡착되었다. 따라서, $CO_2$분해 반응에 Sr 페라이트를 적용할 경우, 사용 조건에 따라 Sr:Fe의 조성비를 제어할 필요가 있다.
