摘要:
以模板牺牲法合成的氮掺杂中空石墨烯球(Nitrogen doped hollow graphene spheres,NHGSs)为基体,通过硼氢化钠还原前驱体氯铂酸,在NHGSs上负载Pt纳米颗粒,获得NHGSs/Pt催化剂;采用场发射扫描电子显微镜、透射电子显微镜、X射线衍射仪、拉曼光谱分析仪、N2吸/脱附仪、X射线光电子能谱和电感耦合等离子体发射光谱仪对NHGSs及NHGSs/Pt进行形貌和结构表征,并测试其在酸性和碱性电解液中的电化学性能。结果表明:NHGSs和NHGSs/Pt具有超大的比表面积以及明显的介孔结构,有利于电荷转移并提高相应的电化学性能;在碱性电解液中,在NHGSs上负载质量分数9.72%Pt的NHGSs/Pt 2催化剂的ORR的起始电位为1.0805 V、半波电位为0.8075 V;在酸性电解液中,NHGSs/Pt 2催化剂的HER的过电位为53.5 mV;在Pt实际负载量只有9.72%的情况下,NHGSs/Pt催化剂的性能就能达到甚至超过质量分数20%商用材料Pt/C的性能。该研究为提升电极材料的催化活性、降低贵金属用量提供了新的思路。
