随着化石资源的日益枯竭,寻求可替代清洁能源已成为全球重大课题。生物质是一种可再生的清洁能源,目前人们尝试通过利用生物质转化缓解日益增长的能源需求。杂多酸是应用在清洁工艺中的重要催化剂,结构和酸度的设计调变性及较高的热稳定性,使其广泛用于生物质的水解转化反应平台。目前固体杂多酸在水溶剂、有机溶剂及两相体系中降解生物质有着各自不同的优缺点。本文综述了杂多酸在不同反应体系中水解转化生物质制备精细化学品的研究进展,并对其在生物质水解转化利用中的应用前景进行了展望。
With the depletion of fossil resources, the search for alternative clean energy has become a major global issue. Biomass is a renewable, clean source of energy and currently people are trying to mitigate the growing demand for energy by using biomass conversion. Heteropolyacid is an important catalyst used in the cleaning process. Its structural and acidity design variability and high thermal stability make it widely used in the hydrolysis reaction platform of biomass. At present, solid heteropolyacids have different advantages and disadvantages in degrading biomass in aqueous solvents, organic solvents and two-phase systems. This review summarizes the progress in the preparation of fine chemicals by hydrolytic conversion of heteropoly acids in different reaction systems and prospects for their application in the hydrolysis and conversion of biomass.
