Advances in Selective Hydrogenation of 5-Hydroxymethylfurfural over Heterogeneous Metal Catalysts

Biomass is an excellent renewable organic energy in nature. 5-hydroxymethylfurfural (HMF) is a significant platform chemical derived from biomass. It can be obtained from biomass and has the potential to produce high value-added derivatives. For the past few years, the chemocatalysis pathway has been extensively studied and is the main pathway of HMF transformation. In this paper, the influence factors and reaction mechanisms of different catalyst types on HMF hydrogenation processes were discussed. The latest progress on the efficient catalytic system using hydrogen, alcohol and other hydrogen sources to catalyze HMF was introduced. Future research prospects of catalytic hydrogenation of HMF were also prospected.
