As an important technology in fine chemical production,the selective hydrogenation of α,β-unsaturated aldehydes has attracted much attention in recent years.In the process of α,β-unsaturated aldehyde hydrogenation,a conjugated system is formed between＞C=C＜and＞C=O,leading to hydrogenation at both ends of the conjugated system,which competes with each other and results in more complex products.Therefore,improving the reaction selectivity is also difficult in industrial fields.Recently,many researchers have reported that surface-active sites on catalysts play a crucial role in α,β-unsaturated aldehyde hydrogenation.This review attempts to summarize recent advances in understanding the effects of surface-active sites(SASs)over metal catalysts for enhancing the process of hydrogenation.The construction strategies and roles of SASs for hydrogenation catalysts are summarized.Parti-cular attention has been given to the adsorption configura-tion and transformation mechanism of α,β-unsaturated aldehydes on catalysts,which contributes to understanding the relationship between SASs and hydrogenation activity.In addition,recent advances in metal-supported catalysts for the selective hydrogenation of α,β-unsaturated aldehydes to understand the role of SASs in hydrogenation are briefly reviewed.Finally,the opportunities and challenges will be highlighted for the future development of the precise construction of SASs.
