The application of heteroatom-doped graphene for photochemical and electrochemical reactions is primarily hindered by the lack of a controllable and facile synthesis strategy. In this work, few-layer CoN-graphene (1.8 nm thickness) with atomic Co has been fabricated via pyrolysis exfoliation. The half wave potential of CoN-graphene reaches 0.875 V vs. RHE, and the corresponding direct methanol fuel cell performance is 100% (higher than that of the commercial Pt/C catalyst), demonstrating potential for practical application in energy conversion devices.

从有前途的类石墨超分子中合成以原子分离的钴锚定的石墨烯

杂原子掺杂石墨烯在光化学和电化学反应中的应用主要受到缺乏可控且简便的合成策略的阻碍。在这项工作中,通过热解剥离制备了带有原子 Co 的少层 CoN-石墨烯(1.8 nm 厚)。CoN-石墨烯的半波电位达到0.875 V vs. RHE,相应的直接甲醇燃料电池性能为100%(高于商业Pt/C催化剂),展示了在能量转换装置中的实际应用潜力。
