| 摘 要： | 设计合成了一种多壳层中空多孔结构的磷化铁(FeP)微球, 通过扫描电子显微镜(SEM)、 透射电子显微镜(TEM)、 X射线衍射(XRD)和X射线光电子能谱(XPS)对微球的表面形貌和物相组成等进行表征, 并通过电化学工作站测试了材料的析氢性能. 结果表明, FeP微球和掺杂导电剂碳纳米管(CNT)后的FeP/CNT复合电催化剂在宽pH范围的电解液中均展现出了优异的电催化活性, 在酸性、 碱性和中性条件下析氢反应过程中的塔菲尔斜率分别为55.0, 64.9, 163.2 mV/dec, 当电流密度达到10 mA/cm 2时, 过电势仅分别为97, 169, 495 mV(vs. RHE), 且表现出了超长的循环稳定性.

| Abstract: | Multi-shell hollow microspheres of iron phosphide(FeP) were synthesized by directly phosphorization of iron oxide microspheres. The prepared microstructures were characterized by SEM, TEM, XRD and XPS. Then their performance for hydrogen evolution reaction(HER) of FeP was investigated in a standard three-electrode system. The results show that the FeP/CNT composite doped with carbon nanotube(CNT) exhibit good catalytic behavior towards HER not only at extreme pH values(0 and 14), but also in neutral medium(pH=7), the Tafel slope are 55, 64.9, 163.2 mV/dec in 0.5 mol/L H2SO4, 1.0 mol/L KOH and 1.0 mol/L Na2SO4, respectively. When the current density reaches 10 mA/cm 2, the overpotentials are 97, 169, 495 mV(vs. RHE), respectively. |
