Abstract
Highly efficient Pt–Fe/γ-Al2O3 catalysts for preferential oxidation of CO in excess of H2 (CO-PROX) were prepared by utilizing single-atom Fe species as active sites for O2 activation, which exhibited high catalytic activity and selectivity from 25 °C to 200 °C, with the highest Pt specific rate of Pt-based catalysts for CO-PROX.
