Abstract
Biomass has attracted much attention because of its clean and renewable characteristics.
The conversion of biomass into various fine chemicals and high value-added fuels is
one of the important ways to solve the energy shortage and environmental pollution. 2,5-furan
dicarboxylic acid (FDCA), a kind of important and promising new bio-based monomer, has
attracted the attention of many researchers due to its wide applications in different industries.
Therefore, many efforts have been made over various metal catalysts for FDCA production
from this biomass-derived platform chemical, 5hydroxymethylfurfural (HMF). In this review,
we introduced the reaction pathways of the aerobic oxidation of HMF to FDCA and summarized
the recent progress of different catalysts and catalysis for HMF aerobic oxidation. Catalytic
performance and reaction pathways are discussed in detail. Finally, conclusions and the
remaining challenges are proposed and further prospects are presented in view of the technical aspects.

Abstract
Biomass energy has attracted much attention because of its clean and renewable
characteristics. At present, C2–C3 polyols such as glycerol, 1,2-propanediol, and ethylene
glycol, widely used as platforms for downstream chemicals or directly used as chemicals
in diversified industries, mainly depend on the petrochemical industry. In terms of the
feedstock for C2–C3 polyol production, the C3-derived glycerol is a side product during
biodiesel synthesis, whereas the C5-derived xylitol and C6-derived sorbitol can be mainly
obtained by hydrolysis–hydrogenation of hemicellulose and cellulose from lignocellulosic
biomass, respectively. In this review, we summarize the catalysts and catalysis for selective
hydrogenolysis of these polyhydric compounds to C2–C3 polyols and introduce the
reaction pathways for the target polyol formation based on the C3, C5, and C6 polyhydric
alcohol hydrogenolysis. Finally, state-of-the-art technologies are described and the remaining challenges and
further prospects are presented in view of the technical aspects.

Abstract
A series of Ru-(Mn-M)OX catalysts (M: Al, Ti, Zr, Zn) prepared by co-precipitation were investigated in the hydrogenolysis of xylitol in water to ethylene glycol, propylene glycol and glycerol at 200 °C and 60 bar of H2. The catalyst promoted with Al, Ru-(Mn-Al)OX, showed superior activity (57 h−1) and a high global selectivity to glycols and glycerol of 58% at 80% xylitol conversion. In comparison, the catalyst prepared by loading Ru on (Mn-Al)OX, Ru/(Mn-Al)OX was more active (111 h−1) but less selective (37%) than Ru-(Mn-Al)OX. Characterization of these catalysts by XRD, BET, CO2-TPD, NH3-TPD and TEM showed that Ru/(Mn-Al)OX contained highly dispersed and uniformly distributed Ru particles and fewer basic sites, which favored decarbonylation, epimerization and cascade decarbonylation reactions instead of retro-aldol reactions producing glycols. The hydrothermal stability of Ru-(Mn-Al)OX was improved by decreasing the xylitol/catalyst ratio, which decreased the formation of carboxylic acids and enabled recycling of the catalyst, with a very low deactivation.
