A series of supported Ni-based multifunctional catalysts were prepared and their catalytic performances for n-butanol Guerbet condensation reaction were evaluated. Ni/hydroxyapatite (HAP) shows the best catalytic performance: a selectivity of 2-ethylhexanol reaches 52.4% at an n-butanol conversion of 29.6% at 230 °C. The activity evaluation results indicate that Ni/HAP with both high-density of acid sites and high-density of base sites have higher catalytic performance. Furthermore, the importance of acid-base synergistic catalysis was proved by evaluating the change of the catalytic performance of Ni/HAP catalyst after poisoning the acidic or basic sites using an acid or a base probe molecule.

制备了一系列负载型镍基多功能催化剂，并评价了其对正丁醇Guerbet缩合反应的催化性能。Ni /羟基磷灰石（HAP）表现出最佳的催化性能：在230°C时，正丁醇转化率为29.6％时，2-乙基己醇的选择性达到52.4％。活性评价结果表明，高密度酸位和高密度碱位的Ni / HAP具有较高的催化性能。此外，通过使用酸或碱探针分子对酸性或碱性位点中毒后，评估Ni / HAP催化剂的催化性能变化，证明了酸碱协同催化的重要性。
