| Popis: | A one-step approach was developed to prepare carbon covered alumina (CCA) material by using Al-based MOFs (Al-PCP) as sacrificial template. Pt/CCA nanoparticle catalysts were characterized by using XRD, TGA, XPS, N 2 sorption, SEM, TEM and elemental analysis and revealed that they retained the mesostructure with high Pt dispersion and had a CCA structure. Moreover, after reduced at 800 °C, Pt/CCA-800 afforded the highest enantiomeric excess (84.8%) after chirally modified with cinchonidine at the second time reaction and can be recycled for more than 8 times without distinct loss of activity or enantioselectivity in the asymmetric hydrogenation of ethyl 2-oxo-4-phenylbutyrate. |
