摘　　要：合成高级醇是将煤、天然气、生物质、CO/CO_(2)等非石油资源转化为液体燃料和高附加值化学品的重要途径之一,对推动煤炭清洁高效利用、CO_(2)资源化利用具有重要意义。近年来,通过改性费托合成催化剂来合成高级醇的研究取得了重要进展,催化剂性能明显提升。因材料廉价易获取且反应机理可借鉴费托合成,Fe基催化剂成为研究热点,但基础理论研究仍待完善。本文概述了近期高级醇合成Fe基催化剂最新的研究进展,重点综述了Fe基催化剂、FeCu基催化剂在合成高级醇反应中活性位点的性质和反应机理。梳理了碱金属、过渡金属、非金属改性对催化剂构效关系的影响,及其对提高催化剂催化活性、高级醇选择性、稳定性的作用。对比了SiO_(2)、Al_(2)O_(3)等常用载体的作用。按浸渍法、特殊结构、复合材料等分别对Fe基催化剂制备方法进行了系统性剖析。The synthesis of higher alcohols is a significant approach for converting non-petroleum resources like coal,natural gas,biomass,CO/CO_(2),and others into liquid fuels and high-valued chemicals,which holds great importance in promoting the clean and efficient utilization of coal and CO_(2).In recent years,there have been remarkable achievements in the research of modified Fischer-Tropsch synthesis catalysts for higher alcohol synthesis,giving significant enhancements in catalytic performance and selectivity for higher alcohols.Fe-based catalysts have emerged as a research focus in recent years due to their low cost and easy access,and their reaction mechanisms can be drawn upon that of Fischer-Tropsch synthesis.However,basic theoretical research still requires to be strengthened.This article presents an overview of the latest research progress on Fe-based catalysts,with a particular emphasis on the properties and reaction mechanisms of active sites in the synthesis of higher alcohols using Fe-based and FeCu-based catalysts.This article reviews the impact of alkali metals,transition metal additives,and nonmetallic doping on the structure-activity relationship of catalysts,as well as on enhancing the catalytic activity,higher alcohol selectivity,and catalyst stability.Comparisons were made for commonly used carriers such as SiO_(2)and Al_(2)O_(3).A systematic analysis of the preparation methods of Fe-based catalysts is presented in terms of the impregnation method,special structure design,and material composite.
