Abstract

Abstract: The conversion of carbon monoxide and hydrogen, generally called synthesis gas, to higher alcohols has gained recent attention. Alcohols can be either transformed into other value‐added products such as ethers or used directly as fuels or fuel additives. Various types of catalysts have been prepared and investigated for the hydrogenation of CO to higher alcohols and improvements are in progress to find a robust catalyst with high activity and selectivity towards higher alcohols. In particular, the role of the bimetallic catalyst having two active sites contributing efficiently to higher alcohol synthesis has been a focus in recent years. Herein, the recent development in bimetallic catalyst preparation and the investigations of the reaction mechanism in CO hydrogenation have been reviewed. Abstract : Teamwork : The synthesis of higher alcohols, which are useful chemical feedstock intermediates, from carbon monoxide hydrogenation is an attractive research area in recent years. In the bimetallic catalyst, one metal dissociates CO and its hydrogenation leads to chain growth, while the second metal acts as an oxygenation site. The co‐existence of two active metals in close proximity helps to improve the selectivity towards higher alcohols.
