摘　　要：生物质作为一种绿色可再生资源,具有替代化石资源以生产高价值化学品和生物燃料的潜力.由于生物质原料中含氧量较高,因此加氢脱氧(HDO)反应成为其转化过程中的关键步骤.氢碘酸(HI)由于其强亲核性和还原性,能够在温和条件下有效催化生物质的氢解,并且在某些生物质转化过程中,可实现无金属催化剂的应用.本文综述了“HI-金属催化剂-H_(2)”催化体系及“HI-氢供体”无金属催化体系在生物质HDO反应中的研究进展,今后对HI体系的探究应当关注机理研究,扩大HI在生物质定向转化的利用范围,重视反应过程对环境的影响.Biomass,as a green and renewable resource,has the potential to replace fossil resources for the production of high-value chemicals and biofuels.Due to the high oxygen content in biomass feedstocks,hydrogenolysis(HDO)reactions become a key step in their conversion process.Hydroiodic acid(HI)can effectively catalyze the hydrogenolysis of biomass under mild conditions due to its strong nucleophilicity and reductive properties,and in some biomass conversion processes,it can achieve the application of metal-free catalysis.This article reviews the research progress of the“HI-metal catalyst-H_(2)”catalytic system and the“HI-hydrogen donor”metal-free catalytic system in biomass HDO reactions.Future explorations of the HI system should focus on mechanism studies,expand the application scope of HI in the directed conversion of biomass,and pay attention to the environmental impact of the reaction process.
