标题:一种用于催化氧卤化天然气提质的活化tic-Sic复合材料
摘要:烷烃氧基卤化已成为一种有吸引力的催化途径,可用于选择性天然气功能化成重要的商品化学品,例如甲基卤化物或烯烃.但是,几乎没有系统显示出在这些反应中具有活性和选择性.在这里,我们确定了一种新型且高效的tic-Sic复合材料,可用于甲烷和乙烷的氧卤代反应.详细的表征阐明了在反应条件下产生tio 2-Tic-Sic的选择性活化的动力学和机理.该催化剂的性能优于报道得最好的催化剂之一的本体tio 2,选择性高达85%,甲基卤化物或乙烯的钛比空时产率提高了3倍.这归因于活性tio 2 原位反应生成的气相嵌入导热sic基体中,有利于散热,从而改善了选择性控制.
