Synthesis of a petroleum asphalt-based nitrogen/sulfur doped porous carbon material and its use as the counter electrode of dye-sensitized solar cells

Funds: National Natural Science Foundation of China (21908245, 21776308, 21576289); Science Foundation of China University of Petroleum, Beijing (2462018YJRC009, 2462017YJRC051).
  • 摘要: 以富含稠环芳烃的石油沥青为碳源,通过C3N4模板剂自分解策略,原位调控了石油沥青转变为炭材料过程中的孔结构及表面杂原子,定向制备得到了具有超大孔体积(4.49 cm3/g)的富氮/硫掺杂多孔炭材料。基于该材料表面丰富的硫氮杂原子及边缘拓扑缺陷结构,在还原I3-离子上展现出了优异的电催化性能。当应用于染料敏化太阳能电池对电极时,取得了7.91%的光电转化效率,可以媲美传统贵金属Pt材料,有望成为一种廉价高效的非Pt基对电极材料,同时也为石油沥青的高附加值利用提供了新的途径。
