Summary: The conversion of biomass into platform chemicals, value-added chemicals, or fuels is crucial for sustainability and carbon neutrality. Functionalized metal catalysts are preferred over biological enzymes due to their stability, recyclability, and ease of separation. 2-Methyltetrahydrofuran (MTHF) is an important sugar-derived platform chemical that can be used as a green solvent, fuel additive, or starting material for synthesizing downstream chemicals. This review discusses the challenges and catalytic conversion of biomass to MTHF on precious and non-precious metal-based catalysts, as well as the subsequent conversion of MTHF to value-added downstream chemicals.

Summary: In this study, the introduction of sulfur species to the Ni/SiO2 catalyst via loading NiSO4 was adopted to inhibit hydrogenation of the furan ring in FA, leading to the conversion of FA to CPO via ring-opening route. The results showed that the co-existence of NixSy and metallic Ni species effectively hindered hydrogenation of the furan ring, decreasing the yield of THFA and shifting the major product to CPO. However, the enhanced acidic sites also catalyzed polymerization of reaction intermediates, competing with the production of CPO.

Summary: The study focuses on catalyst deactivation and carbon loss in furfural conversion in the aqueous phase. By synthesizing Cu catalysts with alkali or alkaline earth metal additives, it was found that these additives inhibited condensate formation significantly, likely due to the stabilization effect of important carbocation intermediates. Characterization techniques revealed that the condensates on catalyst surfaces were highly conjugated polymers resulting from the polymerization of furfuryl alcohol.
