以间苯二酚、苯酚与甲醛为前体,合成了一种中空石墨碳材料(hollow graphitic carbon, H GC). 透射电镜(TEM)、N2吸附-脱附和Raman光谱测试结果表明,所制备的HGC为中孔结构, 平均孔径为36 nm. 与商品Vulcan XC-72R相比, HGC中孔结构丰富,石墨化程度高. 分别以H GC和XC-72R为载体制备了总金属载量为45%的PtSn/C电催化剂, X射线衍射和TEM结果表明这两个样品的平均粒径和晶格常数相近. 单池性能测试表明,以45%PtSn/HGC为阳极催化剂的直接乙醇燃料电池的最大功率密度达到了62 mW/cm2,与PtSn/XC-72R的54 mW/cm2相比提高了近15%.
