1) Catalyst composition covered 0.3%of Pt and 10.0%of Co balanced with Si O2 support.

The catalyst synthesis methods and CO chemisorption results are listed in Table 1.The bimetallic catalysts synthesized by different methods showed similar CO uptake，which was slightly higher than that of the monometallic Co catalyst.This suggests that the trace Pt has little influence on the number of active sites on the surfaces of the reduced catalysts，and the monometallic and bimetallic co-based catalysts would have the similar number of active sites.
