摘要：
Valorization of lignocellulosic biomass is expected to contribute to the realization of a carbon-neutral, sustainable society. In our previous work, a charcoal-supported Pt catalyst was found to be more active than other charcoal-supported metal catalysts (Rh, Pd, and Ru) for the conversion of Japanese cedar to aromatic monomers in supercritical water (yield = 17.4%). Here, we examined the effects of different support materials (i.e., active carbon, alumina, zirconia, and titania) to improve the aromatic monomer yield obtained using Pt catalysts. All of the Pt-based catalysts promoted aromatic monomer production from lignocellulosic biomass. Among them, the titania-supported Pt catalyst (Pt/TiO2) was found to afford the greatest yield (36.2%). Reusability testing revealed that the aromatic monomer yield obtained with Pt/TiO2 was greater than 25% at the fourth recycle. [GRAPHICS] .
