摘要
通过电沉积方法制备了Ni-W-P合金,系统研究了硫酸镍浓度、钨酸钠浓度、次亚磷酸钠浓度、热处理温度等条件对Ni-W-P合金电极析氢活性的影响,并利用扫描电镜、X射线荧光光谱仪等技术对样品的表面形貌和组成等物理性质进行表征。实验结果表明:Ni-W-P合金电极是微生物电解池产氢技术的优良阴极材料,在外加电源0.9V条件下,其最大氢气产率为1.09m3/(m3.d),相应的电流密度和COD去除率分别为131A/m3与91.2%。
A new alloy material nickel-tungsten-phosphorus （Ni-W-P） was obtained by electrodeposition. The effects of experimental conditions, such as heat treatment, nickel sulfate concentration, Sodium Tungstate concen- tration, Sodium hypophosphite concentration, on the catalytic activity of Ni-W-P alloys for hydrogen evolution reaction were systematically studied. The morphology and chemical components of the catalyst were characterized by scanning electron microscopy （SEM） and X-Ray Fluorescence （XRF）. The results show that Ni-W-P is an excellent cathodic material for the hydrogen production by microbial electrolysis cell. At an applied voltage of 0.9V, MEC with Ni-W-P cathode obtained a maximum hydrogen production rate of 1.09m3/（ m3·d） with current density of 131A/m3 and COD removal of 91.2%.
