Abstract
- Hydrodeoxygenation (HDO) for upgrading biomass usually requires high temperature and high H<subscript>2</subscript> pressure. Herein, g-C<subscript>3</subscript>N<subscript>4</subscript>-supported Pd–Au bimetallic nanoparticles are reported as an efficient catalyst for the HDO of vanillin, a typical biomass-derived compound, and some other aromatic aldehydes. With the catalyst and formic acid as the hydrogen donor, the reaction occurs at room temperature and under atmospheric air, and a satisfactory yield of the desired product was achieved within 1 h. A two-phase solvent of H<subscript>2</subscript>O and EA was used, and the catalyst could be reused at least 5 times. The superior performance of PdAu/g-C<subscript>3</subscript>N<subscript>4</subscript> compared to monometallic catalysts could be mainly ascribed to the synergistic catalysis inside the catalyst, which was explored via characterization analysis.
