英文摘要Facileoxidation is a promising technology to valorize lignocellulosicbiomass toward high-value chemicals and cellulose. However, the carbonefficiency is restricted by inevitable dissolution and conversionof carbohydrates and the condensation and degradation of lignin andmonophenolics. Herein, we report the use of CuO nanoparticles (NPs)to oxidatively fractionate lignocellulose with O-2 in aqueousNaOH under mild conditions, achieving over 80% carbon efficiency.Lignin was converted to aromatic aldehyde monomers (up to 48.6 wt%, mainly vanillin and syringaldehyde), and the yield can surpassthe theoretical value (on the basis of the beta-O-4 bond content)due to cleavage of other bonds. This was proven by several model compoundswith different interlinkages. All hemicelluloses were transformedtoward water-soluble small acids (mainly oxalic acid). As it was protectedby the complexation of Cu cations, up to 80% cellulose was obtainedas a white crystalline residue with high purity (>95%), which haspotential applications in the production of materials and chemicals.
