采用溶胶-凝胶法制备了Pd/Si(Zr)O2双功能催化剂及其分别含Cr、Ni或La助剂的催化剂，评价了催化剂在丙酮一步法合成甲基异丁基酮（MIBK）反应中的催化性能。结果表明：引入助剂Ni后，Ni将催化剂的丙酮转化率从25.6%提高到38.5%，但MIBK选择性稍有降低；而引入助剂La后，催化剂的MIBK选择性从58.60%提高到70.84%，但对丙酮转化率没有改进。
採用溶膠-凝膠法製備瞭Pd/Si(Zr)O2雙功能催化劑及其分彆含Cr、Ni或La助劑的催化劑，評價瞭催化劑在丙酮一步法閤成甲基異丁基酮（MIBK）反應中的催化性能。結果錶明：引入助劑Ni後，Ni將催化劑的丙酮轉化率從25.6%提高到38.5%，但MIBK選擇性稍有降低；而引入助劑La後，催化劑的MIBK選擇性從58.60%提高到70.84%，但對丙酮轉化率沒有改進。

Bifunctional catalysts Pd/Si(Zr)O2 including that of containing prompter Cr, Ni or La were prepared by the sol-gel method, and their catalytic performances for one-step synthesis of methyl isobutyl ketone (MIBK) from acetone were evaluated. The results showed that the addition of Ni could improve the conversion of acetone from 25.6% to 38.5%, but reduce the selectivity of MIBK slightly;and the introduction of La could enhance the selectivity of MIBK from 58.60%to 70.84%, but not improve the conversion of acetone.
