摘      要：Herein,we introduced a nitrogen-alkali lignin-doped phenolic resin(N@AL_(n)PR)to produce palladium nanoparticles through an in situ reduction of palladium in an aqueous phase,without the need for additional reagents or a reducing *** phenolic resin nanospheres and the resulting palladium nanoparticles were extensively *** lignin created a highly conducive environment for nitrogen incorporation,dispersion,reduction,and stabilization of palladium,leading to a distinct catalytic performance of palladium nanoparticles in vanillin *** specific conditions of 1 mmol of vanillin,40 mg of catalyst,1 MPa H_(2),90°C,and 3 h,the optimized Pd/N@AL_(30)PR catalyst exhibited a nearly complete conversion of vanillin,98.9%selectivity toward p-creosol,and good stability for multiple ***,an environmentally friendly lignin-based catalyst was developed and used for the efficient hydrodeoxygenation conversion of lignin-based platform compounds.
