摘要
采用恒电流沉积法制备了钯/泡沫镍电极,通过扫描电子显微镜(SEM)、X-射线光电子能谱(XPS)及X-射线衍射(XRD)分析了其表面形貌、成分及晶体结构,并探讨了对高氯酸盐的电催化还原效果。结果表明,金属钯成功负载在泡沫镍基体表面,制备的钯/泡沫镍电极表面分布均匀,具有一定的比表面积。在高氯酸盐初始浓度0.5mmol/L、工作电流50m A、温度为25℃条件下,高氯酸盐的去除率可达到87.0%。同时,制备的钯/泡沫镍电极具有良好的稳定性。
The Pd/foam-Ni electrode was fabricated by electrodeposition with constant currents and also characterized by scanning electron microscope(SEM), X-ray photoelectron spectroscopy(XPS) and X-ray diffraction(XRD). And then the degradation of perchlorate by using Pd/foam-Ni electrode was discussed in details. The results showed that Pd particles had been successfully loaded on the surface of foam-Ni substrate. The Pd/foam-Ni electrode presented with uniform morphology and certain specific surface area. At the condition of perchlorate concentration 0.5 mmol/L, current 50 mA and reaction temperature 25℃, the removal of ClO_4~- could reach to 87.0%. Additionally, the fabricated Pd/foam-Ni electrode presented with good stability.
