单原子催化剂催化生物质衍生物选择性加氢的研究进展

ADVANCES IN SELECTIVE HYDROGENATION OF BIOMASS DERIVATIVESCATALYZED BY MONATOMIC CATALYSTS

生物质是以碳源形式存在的可再生资源,其平台化合物及衍生物的升级利用可得到能源和精细化工产品。多相催化剂在生物质资源的转化中起到重要作用,其中不乏纳米催化剂和单原子催化剂的参与。由于木质纤维素的含氧量较高,不能直接作为工业应用原料,因此需要还原反应来降低其含氧量。加氢反应是降低木质纤维素衍生分子中O C比、提高H C比的重要方法。本研究将综合讨论单原子催化剂在呋喃类、α,β-不饱和醛酮和木质素类平台化合物选择性加氢中的应用。

Biomass is a kind of renewable resource in the form of carbon source,and its platform compounds and derivatives can be used to upgrade energy and fine chemical products.Heterogeneous catalysts play an important role in the conversion of biomass resources,many of which involve nano-catalysts and monatomic catalysts.Because of the high oxygen content of lignocellulose,it can not be directly used as industrial raw material,so reduction reaction is needed to reduce its oxygen content.Hydrogenation is an important method to decrease the ratio of O C and increase the ratio of H C in lignocellulosic molecules.The application of monatomic catalysts in selective hydrogenation of furans,unsaturated aldehydes and lignin platform compounds would be comprehensively discussed.
