In preferential CO oxidation in H2-rich gas, K-Pt/Al 2O3 (K/Pt =10) was very effective in decreasing CO concentration below 10 ppm in the 375-410 K range, and the turnover frequency of the K-Pt/Al2O3 was 20 times as high as that of Pt/Al 2O3 at 353 K; furthermore, the activity of CO oxidation was promoted drastically by the presence of H2.
