摘要:

通过水热法在碳布基底上生长了氢氧化镍纳米片陈列[Ni(OH)2 NAs/CC], 并以其为前驱物, 合成了Ni3N NAs/CC纳米片阵列, 构建了无需黏结剂的三维自支撑电极. 采用X射线衍射(XRD)、 X射线光电子能谱(XPS)、 扫描电子显微镜(SEM)和透射电子显微镜(TEM)等对复合电极表面的结构、 组成和形貌进行了测试和表征. 结果表明, 与Ni(OH)2 NAs/CC相比, Ni3N NAs/CC电极表面粗糙度和孔隙率变大, 电化学有效面积增加; 线性扫描及Tafel 曲线等电化学测试结果表明, Ni3N NAs/CC电极的析氧活性大幅提高, 析氧电位下降可达280 mV, 且表现出了良好的稳定性.

Abstract:

Ni(OH)2 nanosheet arrays on carbon cloth[Ni(OH)2 NAs/CC] were synthesised via hydrothermal treatment. Then Ni3N nanosheet arrays on carbon cloth(Ni3N NAs/CC) were prepared through the nitridation of corresponding Ni(OH)2 NAs/CC precursor with NH3, thus polymer binder free three dimensional self-supporting electrode was established. The structure and morphology of the composite electrode materials were investigated by X-ray diffraction(XRD), X-ray photoelectron spectroscopy(XPS), scanning electron microscopy(SEM) and transmission electron microscopy(TEM) analyses. The results indicate that the porosity, roughness and electrochemical effective area of Ni3N NAs/CC electrode surface are increased. The activities for the oxygen evolution reaction(OER) of the Ni3N NAs/CC were explained by recording linear scanning voltammograms and Tafel plots, the results indicate that the activity for OER is effectively increased and the overpotential for oxygen evolution could be lowered by approximately 280 mV. In the meantime, Ni3N NAs/CC electrode exhibited good durability.
