By　employing　N,　N-dimethylacetamide　(DMAC)　as　solvent　and　tetramethylammonium　hydroxide　(TMAOH)　as　precipitant,　La0.6Sr0.4MnO3　perovskite　with　high　surface　area　of　48　m2　g−1　was　successfully　synthesized　via　a　facile　coprecipitation　method.　The　results　show　that　high　compositional　homogeneity　of　precipitate　was　obtained,　which　contributed　to　the　low　crystallization　temperature　and　thus　high　surface　area.　The　resulting　La0.6Sr0.4MnO3　exhibited　higher　activity　than　those　prepared　by　other　traditional　methods　for　methane　oxidation,　which　could　be　ascribed　to　the　low　apparent　activation　energy　originated　from　high　surface　area.　©　2017
