Fabrication of hollow-structured FeOx-MnOx oxidative catalysts with ultra-large surface area

In this work, hollow-structured MnO x and FeO x -MnO x were synthesized by self-template route and applied for CO oxidation . FeO x -MnO x exhibited better catalytic activity than MnO x . It could convert 79.1% CO at 20   °C and had a higher CO conversion during the temperature ramping. The FeO x species could react with HCl and greatly helped to increase the specific surface area (428.5   m 2   g −   1 ) and pore volume (0.82   cm 3   g −   1 ) of the catalyst. The reserved FeO x in the FeO x -MnO x sample enhanced the redox properties and increased the amount of reactive oxygen species.
