Description
Summary:The catalytic conversion of 5‐hydroxymethylfufural (HMF), one of the vital platform chemicals in biomass upgrading, holds great promise for producing highly valuable chemicals through sustainable routes, thereby alleviating the dependence on fossil feedstocks and reducing CO2 emissions. The reductive upgrading (hydrogenation, hydrogenolysis, ring‐opening, ring‐rearrangement, amination, etc.) of HMF has exhibited great potential to produce monomers, liquid fuel additives, and other valuable chemicals. Thermocatalytic conversion has a significant advantage over photocatalysis and electrocatalysis in productivity. In this Review, the recent achievements of thermo‐reductive transformation of HMF to various chemicals using heterogeneous catalytic systems are presented, including the catalytic systems (catalyst and solvent), reaction conditions, (reaction temperature, pressure, etc.), and reaction mechanisms. The current challenges and future opportunities are discussed as well, aiming at guiding the catalyst design and practical scalable productions. Some like it hot: Biomass‐derived 5‐hydroxymethylfurfural (HMF) is viewed as a crucial platform molecule to produce fuel and valuable chemicals. This Review provides a systematic summary of recent achievements in reductive transformation of HMF into twelve chemicals via heterogeneous thermocatalysis, mainly highlighting the involved catalytic systems and reaction mechanisms. The current challenges and the direction for future study are also discussed.
