N-doped carbon support can increase “nanoparticle (NPs)-support interaction” and generate more defective sites to promote prepared catalyst’s performance. Adenine can provide a large amount of nitrogen resources and possesses great potential in preparing N-doped carbon support. Herein, in this study, we prepare a catalyst through supporting Pd₃Ru nanoparticles on an adenine-originated N-doped carbon support. Electrochemical results indicate that the adenine-originated N-doped carbon supporting on Pd₃Ru NPs (Pd₃Ru/NC) shows high catalytic performance in comparison with Pd/NC and Pd/C in glycerol electrooxidation. Furthermore, the activity, poisoning tolerance, long durability and stability of the Pd₃Ru/NC catalyst are greatly promoted. These results may be brought about by defective sites of adenine-originated NC favoring good NPs dispersion and nucleation, and the bifunctional effects of Pd₃Ru alloy, as well as the good interaction between NPs and NC support. All results clearly demonstrate that as-prepared adenine-originated NC support can greatly improve catalytic performance.
