摘要: 通过水热合成法，以高纯泡沫镍为生长基底制备了Cu9S5超长纳米线阵列，这种纳米线阵列具有较大的长径比，可以为电催化析氧反应提供更多的活性位点，这可以提高催化剂在碱性条件下的OER催化性能。我们利用X射线衍射仪、X射线光电子能谱、扫描电子显微镜和透射电子显微镜对催化剂的组成和形貌进行表征，并通过线性扫描伏安曲线、塔菲尔曲线、计时安培分析法等对其电催化析氧性能进行了系统研究。结果表明，在1.0 mol/L KOH电解液中，该电极表现出优异的电催化析氧性能，在电流密度10 mA/cm2时过电位仅为295 mV，塔菲尔斜率为80 mV/dec，并具备仅4.9 W的电荷转移电阻。因此，该Cu9S5超长纳米线在析氧电催化剂中具备潜在的应用价值。
Abstract: Cu9S5 ultra-long nanowires array was synthesized by hydrothermal method with high-purity nickel foam growth substrate. The ultra-long nanowire array can provide more active sites for OER by a large length to diameter ratio. The composition and morphology structure of the catalyst were characterized by X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy and transmission electron microscopy. The electrocatalytic properties for OER were studied by linear sweep voltammetry, Tafel curve and chronopotentiometry. The results show that Ni foam supported Cu9S5 nanowire array exhibits a low overpotential of 295 mV at 10 mA/cm2, a Tafel slope of 80 mV/dec and a charge transfer resistance of 4.9 W in 1.0 mol/L KOH electrolyte. Therefore, the Cu9S5 ultra-long nanowires electrode has potential value in OER (Oxygen evolution reaction) water splitting.
