Facile synthesis of three-dimensionally ordered macroporous silicon-doped La 0.8 K 0.2 CoO 3 perovskite catalysts for soot combustion

Three-dimensionally ordered macroporous (3DOM) silicon-doped La 0.8 K 0.2 CoO 3 perovskite catalysts were successfully prepared by a colloidal crystal templating method. The catalysts showed a well-ordered macroporous structure and exhibited high activity for soot removal.
