摘要：

5.0% ( mass fraction) Pt catalysts supported on periodic mesoporous resols(FDU-14) and ordered mesoporous carbon materials (CMK-3) were prepared using a wet impregnation method, respectively. The catalytic performances of Pt/FDU-14 and Pt/CMK-3 catalysts in the asymmetric hydrogenation of ethyl pyruvate were compared with the commercial Pt/Al2O3 catalyst. Although the commercial Pt/Al2O5 catalyst affords the highest initial activity and enantioselectivity, the Pt/FDU-14 and Pt/CMK-3 catalysts are superior to Pt/Al2O3 in immobilization of platinum under the same conditions. Based on the chemical nature of different supports, the difference in the catalytic performance and stability of three supported Pt catalysts was interpreted for the enantioselective hydrogenation of ethyl pyruvate.
