Study on the catalytic performance of CO-PROX catalyzed by CuO-NiO/CeO2 in H2/CO2 rich atmosphere

    Graphical Abstract
    • Abstract
  • The CuO-NiO/CeO2 catalyst was prepared by step impregnation method. The catalyst was characterized by XRD, BET, H2-TPR, Raman and XPS, and the effects of the calcination temperature of NiO-CeO2 precursor on the physicochemical properties of the catalyst and the selective oxidation of CO in H2/CO2 rich atmosphere were investigated. The results showed that the precursor calcination temperature mainly affected the reduction performance and oxygen vacancy content of the catalyst. When the calcination temperature is 500 ℃, the content of oxygen vacancy in the catalyst is higher, and the catalytic performance is better. When the reaction temperature is 130 ℃, the oxygen excess coefficient is 1.2, and the air speed is 20266 mL/(g·h), the CO conversion rate is 95.9%, and the CO oxidation selectivity is 86.3%.
