Abstract

Ni (Co) doped CeO₂ were prepared via hydrothermal, sol-gel and solid state methods for NO + CO reaction (CO + NO → CO₂ + N₂). The catalysts prepared by hydrothermal method (denoted as NiCe-HT and CoCe-HT) exhibited higher NO elimination efficiency than that by the other two methods due to their novel nanosheets-assembled microsphere structures and higher specific surface areas. Further characterization revealed that the better catalytic performance of NiCe-HT than CoCe-HT benefits from the easier reduction behavior, more oxygen vacancies and abundant vacancy oxygen, leading to the NO complete elimination temperature of 175 ^oC and lifetime more than 20 h. In situ DRIFTS experiments indicated that the addition of Ni and Co into CeO₂ can enhance NO and CO adsorption capacity, unstable intermediates were easier to be generated and converted on NiCe-HT than CoCe-HT. Finally, a possible mechanism for NO+CO reaction was proposed to understand the reaction processes.
