The research progress of solid acid-base catalysts in the reduction of furfural Meerwein-Ponndorf-Verley(MPV)to furfuryl alcohol was reviewed.As a highly commercialized biological platform compound,furfural can be reduced into more economical chemicals by hydrogenation.MPV reduction is favored in the field of bio-refining because of its mild conditions,safety and environmental protection.The typical reactions of MPV and the formation of six-membered ring transition states are introduced,and the research progress of different solid acid-base catalysts in the reduction of furfural to furfuryl alcohol with MPV is summarized,the excellent MPV reduction performance of zirconium/hafnium-based catalysts has been widely studied.A summary of solid acid-base catalysts in this field and the main problems and solu-tions in this field are pointed out,at the same time,the future development of this field is prospected.
