  "abstract": "To realize a sustainable society with circular flows of energy and materials, it is crucial to develop eco-friendly methods to isolate valuable chemical components, such as cellulose, from wood, thereby utilizing woody biomass as a renewable resource. We have devised a one-step delignification process using hydrogen peroxide as a green oxidant. This method selectively breaks down and removes lignin while preserving polysaccharides, especially cellulose, at relatively low temperatures (around 60 ̊C). By evaluating various solvents and catalysts, we demonstrate that a biphasic reaction system comprising aqueous hydrogen peroxide and a hydrophobic solvent enables smooth delignification with organosulfonic acid catalysts bearing a hydrophobic substructure, and reduces the use of hydrogen peroxide and acid catalysts compared to conventional approaches.",
