Abstract Doping with foreign atoms is a powerful technique for modifying the inherent properties of a host materials. In this work, we report a strategy for preparing multiple heteroatom-doped graphene nanoplatelets (GnPs). Poly(anilineboronic acid, PABA), which is one of the conducting polymers, was in-situ grafted to edge-amine functionalized GnPs (A-GnPs) in phosphoric acid. The isolated PABA grafted A-GnPs phosphoric acid salts (PA-GnP salts) were heat-treated at 900 °C under argon atmosphere to yield boron (B)-nitrogen (N)-phosphorus (P) doped GnPs (BNP-GnPs). The structure of the BNP-GnPs was confirmed by various techniques, including transmission electron microscopy, scanning electronic microscopy, X-ray photoelectron spectroscopy, Raman spectroscopy and thermogravimetric analysis. The BNP-GnPs demonstrated significantly improved electrocatalytic activity towards the oxygen reduction reaction, suggesting that BNP-GnPs can be one of the best alternatives to precious Pt-based electrocatalysts.

用于增强电催化活性的硼-氮-磷掺杂石墨烯纳米片

摘要 掺杂外来原子是一种改变主体材料固有特性的强大技术。在这项工作中，我们报告了一种制备多杂原子掺杂石墨烯纳米片（GnP）的策略。作为导电聚合物之一的聚（苯胺硼酸，PABA）原位接枝到磷酸中的边缘胺官能化 GnP（A-GnP）。分离出的 PABA 接枝的 A-GnPs 磷酸盐（PA-GnP 盐）在 900°C 下在氩气气氛下进行热处理，得到硼 (B)-氮 (N)-磷 (P) 掺杂的 GnPs (BNP-GnPs) . BNP-GnPs的结构通过各种技术得到证实，包括透射电子显微镜、扫描电子显微镜、X射线光电子能谱、拉曼光谱和热重分析。
