| Abstract: | The effects of alkali metal promoters on the catalytic performance of Pt/γ-Al2O3 for preferential oxidation(PROX) of CO in hydrogen-rich stream were studied. The results showed that doping of alkali metal promoters had different influences on the performance of Pt/γ-Al2O3 catalyst. The doping of Na and K promoters increased the conversion of CO at low temperature. |
