  • 摘要: 以包覆石墨烯的炭化三聚氰胺泡沫作为支撑,通过水热法在三维泡沫炭上原位生长二硫化钼(MoS2)纳米片,合成出一系列的MoS2/石墨烯/泡沫炭复合材料。经XRD和TEM表征,拥有三维网络结构的炭基骨架被厚度为15~20 nm的MoS2纳米片均匀包裹。石墨烯包覆量对析氢性能影响很大,包覆浓度25 mg L-1的R-&CMMS-25析氢性能最佳,在10 mA cm-2电流密度下过电位为163 mV,相应的塔菲尔斜率为76 mV dec-1,相比之前未包覆石墨烯的复合材料,析氢性能得到了很大提升。通过阻抗谱间接表征材料的电子迁移效率,可以看出R&CMMS-25的阻抗值最低,这表明包覆适量还原氧化石墨烯能够加速电子迁移效率并进一步提升析氢性能。
