摘要
研究了钙钛矿型催化剂La1-xSrxMeO3对乙醇氧化脱氢所生成乙醛的反应 ,研究结果显示出x =0 .2时其催化活性最佳 .B位取代后La1-xSrxMeO3的活性次序为La1-xSrxCoO3>La1-xSrxMnO3>La1-xSrxNiO3>
Oxidative dehydrogenation of ethanol to acetaldehyde was studied by use of a flow reactor in temperature range 200～450 ℃ over La 1-xSr xFeO 3 and La 1-xSr xMeO 3(Me=Co.Mn Ni and Fe) the catalytic activiy for acetaldehyde formation increased with x up to the maxinum at x= 0.2.The activity of La 1-xSr xCoO 3>La 1-xSr xMnO 3>La 1-xSr xNiO 3>La 1-xSr xFeO 3.
