One-pot Synthesis of Meso-structured PdCeOx Catalyst for Efficient Low-temperature CO Oxidation under Ambient Condition

Meso-structured PdCeO_x composites with high specific area were successfully fabricated through a facile one-pot co-precipitation approach. The as-prepared materials showed excellent catalytic activities for CO oxidation under ambient condition. The complete CO conversion could be achieved at 25 ^oC, when 3.0 vol% H₂O was introduced into the feed gas.
