초록

Sr hexaaluminate(Sr1-xLaxMnAl11O19-α)와 금속 alkoxide를 전구체로, 1-butanol과 ethylene glycol을 각각 용매로 사용한 sol-gel 법으로 합성하였다. 용매 변화에 따른 Sr hexaaluminate의 물리적 특성을 TG/DTA, XRD 및 N2 adsorption을 이용하여 분석하였다. 합성 후 건조한 시료에 대한 열분해 거동을 분석한 결과는 1-butanol을 용매로 사용하여 합성한 hexaaluminate와 비교할 때, ethylene glycol을 용매로 이용한 경우 용매의 분해반응과 dehydroxylation 반응이 관찰되었고, 결정생성 온도도 상승하였다. Dehydroxylation 반응과 결정생성온도의 상승은 hexaaluminate의 소결현상을 가속시켜 낮은 비표면적의 원인이 되었다. 메탄에 대한 연소 반응으로 표면적 차이가 촉매 활성에 영향을 주었음을 확인하였다.

Sr hexaaluminate(Sr1-xLaxMnAl11O19-α) were prepared by sol-gel method of metal alkoxide with 1-butanol or ethylene glycol as a solvent. The physical properties of prepared hexaaluminates were examined by TG/DTA, XRD and N2 adsorption. When ethylene glycol was used as a solvent, the decomposition reaction and dehydroxylation reaction was observed above 400 ℃ and the temperature of the formation of a crystal structure of hexaaluminate was also increased resulting in small specific surface area and low catalytic activity of methane compared to Sr-hexaaluminate with 1-butanol.
