1-butanol과 ethylene glycol을 이용하여 합성한 Sr hexaaluminate의 물리적 특성 및 메탄 연소 반응에 관한 연구
A Study on Physical Properties and Catalytic Combustion of Methane of Sr Hexaaluminate Prepared using 1-butanol and Ethylene Glycol
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.
