Catalytic conversion is an important route for the utilization of the renewable biomass resources,and the construction of highly efficient catalysts is a crucial step for the catalytic conversion of biomass and its derivatives.The hydrogenation conversion of biomass derived carbonyl derivatives into alcohols or ester compounds is an important step during the catalytic conversion processes of biomass.Due to the mild reaction conditions of the transfer hydrogenation process,the heterogeneous transfer hydrogenation catalysts have broad applications in the conversion of biomass derived carbonyl compound platforms.The transition metal zirconium and hafnium are commonly used as active metals for the transfer hydrogenation reaction.This review summarized the preparation of the zirconium and hafnium based transfer hydrogenation catalysts and their applications in the hydrogenation conversion of biomass derived platforms.Firstly,the preparation of the zirconium and hafnium based transfer hydrogenation catalysts were briefly introduced.Then,zirconium oxide or hydroxide,zirconium/hafnium based catalyst with different ligand(hydroxyl,carboxylic acid,phosphonic acid,sulfonic acid,tungsten acid,amine,organic metal skeleton,zeolite molecular sieve)ligand,the double metal catalyst and the comparative analysis of their catalytic performance,cycle stability and structural mechanism were reviewed in detail,and the performances of these catalysts were compared.Finally,the future perspectives of the catalytic transfer hydrogenation of biomass and the construction of the catalysts were prospected.
