摘要
The FeOx-supported Pd catalyst prepared by co-precipitation has drawn considerable research attention owing to its low-temperature CO oxidation activity. However, Pd utilization should be improved owing to its encapsulation into the support. In this work, atmospheric-pressure cold plasma was employed to synthesize a Pd/FeOx-P catalyst for the first time. The reaction rate of the Pd/FeOx-P catalyst (at 25 °C) is 1.3 times that of the Pd/FeOx-C catalyst prepared by conventional H2 reduction and 3.5 times that in a previous work, owing to the surface enrichment of Pd species, the larger pore diameter of the FeOx support, a higher metallic Pd ratio, and abundant oxygen vacancies.
