The highly active catalysts of nanocomposite K-Co-CeO_2 for soot combustion

摘要

Nanocomposite K-Co-CeO_2 catalysts were synthesized by the controllable micropore-diffused co-reaction method. Due to the size-match nanometre effect between CeO_2 support and active components and formation of NO_2, these cheap nanocomposite catalysts exhibit super catalytic performances which are as good as a supported Pt catalyst under loose contact conditions for soot combustion.
