Because n-butanol as a fuel additive has more advantageous physicochemical properties than those of ethanol, ethanol valorization to n-butanol through homo- or heterogeneous catalysis has received much attention in recent decades in both scientific and industrial fields. Recent progress in catalyst development for upgrading ethanol to n-butanol, which involves homogeneous catalysts, such as iridium and ruthenium complexes, and heterogeneous catalysts, including metal oxides, hydroxyapatite (HAP), and, in particular, supported metal catalysts, is reviewed herein. The structure-activity relationships of catalysts and underlying reaction mechanisms are critically examined, and future research directions on the design and improvement of catalysts are also proposed.
由于正丁醇作为燃料添加剂具有比乙醇更优越的物理化学性质，因此通过均相或多相催化将乙醇转化为正丁醇在最近几十年的科学和工业领域都受到了广泛关注。本文综述了近年来在将乙醇升级为正丁醇的催化剂开发方面取得的进展，包括均相催化剂，如铱和钌配合物，以及多相催化剂，包括金属氧化物、羟磷灰石（HAP），特别是负载型金属催化剂。本文还批判性地考察了催化剂的结构-活性关系和潜在的反应机制，并提出了在催化剂设计和改进方面的未来研究方向。
