| 英文摘要 | Cr(3+) and zr(4+) cation-incorporated hydrotalcites (hts) were prepared by coprecipitation method. corresponding mixed oxide were obtained by the thermal decomposition of hts at 773 k for 8 h and applied in the synthesis of isophorone (ip) from acetone. from the characteristic results, both cr(3+) and zr(4+) were introduced into the lattice of hydrotalcite producing the more disordered ht structures. compared with mg-al mixed oxide. cr and zr modified mixed oxide demonstrated more amount of basic sites and stronger base strength, which were responsible for the improvement of catalytic activity. as a result, both of the modified mixed oxide exhibited ip selectivity of more than 70% under atmospheric pressure.
