Description
Summary:Platinum (Pt)/two-dimensional (2D) carbon nanocomposites with high catalytic performance and stability are mostly fabricated through two-step route, in which the 2D carbon supports are pre-prepared and then Pt nanoparticles are disposed on the surface of 2D carbon supports. Such method needs tedious processes to pre-prepare 2D carbon substrates and the binding between Pt and carbon might be weak. Herein, we report the synthesis of the Pt/carbon nanosheet (Pt/CNS) nanocomposites via a hydrothermal method, in which the formation of CNSs and the loading of Pt nanoparticles occurred almost simultaneously. We find that hydrogen bond can promote Pt nanoparticles anchored and dispersed uniformly on the surface of CNS. The good synergistic effect between Pt and CNS greatly improved the electrocatalytic performance for ethanol oxidation. [Display omitted] •The formation of carbon nanosheet and loading of platinum nanoparticle in platinum /carbon nanosheet composite are simultaneously achieved.•The hydrogen bond was supposed to help C10H14O4Pt link with glucose to form Pt/C nanocomposite.•The surface structure of Pt nanoparticle and the synergy of carbon nanosheet facilitate the good electrocatalysis activity.
