| 摘 要： | 采用溶液中等离子放电法制备出了Pt纳米颗粒,用热氧化刻蚀和水热法成功的对石墨相氮化碳(g-C_3N_4)进行处理进而均匀吸附在科琴黑(KB)表面,最终制备出了Pt/g-C_3N_4/KB纳米复合催化剂。通过XRD分析,扫描电镜,透射电镜和电化学工作站探究了催化剂的组成、结构、颗粒大小以及电化学性能。Pt/g-C_3N_4/KB纳米复合催化剂展现出了良好的甲醇电氧化性能,性能的提升可能是由于g-C_3N_4良好的化学稳定性,N元素的存在改变Pt外层电子结构从而提高催化活性,这些因素提高了Pt的催化效率。

| Abstract: | Pt/g-C3N4/KB was prepared by a facile method, Pt nanoparticles were prepared through solution plasma process, g-C3N4 was exfoliated by thermal oxidation to obtain g-C3N4 nanosheets (g-C3N4 NS), and g-C3N4 NS was treated further by hydrothermal method. The obtained Pt/g-C3N4/KB was characterized by X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. The activity of samples for methanol electrocatalytic oxidation reaction was evaluated by cyclic voltammetry, respectively. The Pt/g-C3N4/KB exhibits much better activity than that of Pt/KB. The improvement may be attributed the excellent chemical stability of g-C3N4, high activity of Pt atoms owing to the N element of g-C3N4, and methanol molecule may be adsorbed to g-C3N4 owing to the hydrogen bond. |
