摘要：
In this study, B, N-codoped graphene nanoribbons (BN-GNRs) were prepared on a large scale via a one-pot hydrothermal method with GNRs and an ammonium fluoroborate (NH4BF4) mixture and served as the support for Pd loading targeted for efficient ethanol electrooxidation. The synthesized Pd/BN-GNRs catalysts were characterized by TEM, XRD, XPS and electrochemical methods. The results showed that the Pd nanoparticles were uniformly loaded on BN-GNRs and the Pd/BN-GNRs exhibited much enhanced electrocatalytic activity and stability compared with Pd/GNRs and Pd/C.
