Turning Renewable Resources into Value: Selective Hydrogenolysis of C–O Bonds with Multifunctional Solid Catalysts

The hydrogenolysis of C–O bonds is a key reaction for converting oxygen-rich resources such as biomass and waste plastics into valuable chemicals. We have developed supported metal catalysts that enable efficient C–O bond cleavage under mild conditions through metal–support cooperation. For example, Pt/Al(PO3)3 selectively catalyzed the hydrogenolysis of phenols to arenes even under low hydrogen pressure (0.1 atm). Solid-state 31P NMR analysis revealed an aluminum tripolyphosphate (ATPP) phase on the catalyst surface, leading to the development of Pt/ATPP with improved arene selectivity. Transfer hydrogenolysis was also achieved using cyclic hydrocarbons such as decalin as hydrogen sources. Furthermore, we developed a bimetallic Ni–Pd/CeO2 catalyst for the chemical recycling of epoxy resins, enabling simultaneous recovery of phenolic monomers and fillers from epoxy resin composites.
