摘要
多金属氧酸盐(Polyoxometalates,POMs)又称多酸,是一种多功能、具有多活性位点和强氧化还原性的固体强酸,在生物质转化过程中,可根据需要在分子水平上对酸强度、酸性质、氧化还原性进行系统调控和设计.介绍多金属氧酸盐的一般性质和催化特性,综述近年来国内外多酸在生物质催化转化中的应用,总结多酸催化降解木质素、纤维素、半纤维素、木质纤维素以及木质纤维素衍生物方面的研究进展,讨论多酸作为基材或配合物与生物质材料结合制备复合催化剂的方法,指出多酸在生物质高值化利用领域面临的挑战,以期为生物质能源开发与高效转化提供研究思路.
Polyoxometalates(POMs)are multifunctional,solid strong acids with multiple active sites and strong redox properties,which can be systematically regulated and designed at the molecular level for the acid strength,acid properties,and redox properties of polymetallic acids in the biomass conversion.This paper introduces the general properties and catalytic characteristics of POMs,reviews the application of POMs in biomass catalysis or modification at home and abroad in recent years,and summarizes the research progress of POMs catalytic degradation,including lignin,cellulose,hemicellulose,lignocellulose and lignocellulose derivatives.In addition,the method of preparing composite catalysts by combining polyacids as substrates or complexes with biomass materials are discussed,challenges based on polyacids in the high value utilization of biomass materials are presented with the aim of providing more efficient conversion ideas for biomass development.
