The hydrogenation of furfural and its derivatives to pentanediol has been widely recognized as a sustainable and green process.In this selective hydrogenation process,the design of highly active and selective catalysts plays a critical role.In this paper,the mechanism of metal-base and metal-acid catalytic reaction is introduced in detail according to acid-base properties of the support.This review describes the latest research progress of catalysts in the hydrogenation of furfural and its derivatives to pentanediol from catalyst support type point of view.And it discusses the effect of strong metal-support interaction between different carriers and metal on catalytic performance.At the same time,the current problems of such as the unclear catalytic mechanism and the inability to large scale production are pointed,and the adjustment of metal dispersion and acid-base properties of the support to further improve the catalytic performance should be the key points for future research.
