摘　　要：混合醇合成要求催化剂具备至少两类活性中心, 一类用于解离吸附CO以生成烷基链, 另一类用于非解离吸附CO以使烷基链含氧化生成醇. 两类中心通过协同作用共同构成混合醇合成所需的双活性中心. 简要综述了近年来合成气制混合醇过程中涉及的双功能催化研究进展, 并以几类典型的催化剂体系为例, 从双活性中心的构筑、典型的双活性中心结构、反应过程中双活中心结构的演变等方面进行了阐述. 混合醇催化剂的研发应从纳米尺度上对催化剂进行设计, 使催化剂表面具有足够多的双活性中心, 并设法稳定催化剂的双活性中心结构.Bifunctional catalysis on dual sites plays an important role in higher alcohol synthesis from syngas.It makes use of two types of active sites of which one type dissociates CO and forms surface alkyl species and the other type catalyzes non‐dissociative CO adsorption for CO insertion and alcohol formation.To improve catalytic activity for higher alcohol synthesis,it is necessary to design dual sites on the atomic scale to give them high stability.The recent advances in higher alcohol synthesis using bifunctional catalysts are reviewed.The design of the dual sites,the structure of the dual sites on several typical catalyst systems,and the structural evolution of the dual sites during reaction are discussed using our latest research results.
