In this work, a very high 1-butanol yield of 23.7% was obtained in a batch reactor using an inexpensive and stable Ni–MgO catalyst under mild conditions (250 °C, 5 h, 2.5 MPa helium). Uniformly distributed Ni species provide strong dehydrogenation and hydrogenation functionalities, whereas the Ni–MgO provides an optimal acidic–basic site for aldol condensation of acetaldehyde. Meanwhile, the typical Guerbet pathway was improved further and the side reactions were restrained over the Ni–MgO catalysts based on our mechanistic studies.

在温和的条件下，在富含地球的Ni–MgO催化剂上，将乙醇有效地一锅重整为1-丁醇

在这项工作中，在温和的条件下（250°C，5 h，2.5 MPa氦气），使用廉价且稳定的Ni–MgO催化剂，在间歇式反应器中获得了23.7％的1-丁醇很高的收率。均匀分布的镍物质具有很强的脱氢和氢化功能，而镍-氧化镁为乙醛的醛醇缩合提供了最佳的酸性-碱性位点。同时，根据我们的机理研究，典型的Guerbet途径得到了进一步改善，并且副反应比Ni-MgO催化剂受到抑制。
