摘要： 以开发高效水分解制氢和葡萄糖检测电极材料为目标，采用电化学沉积法在廉价的商业石墨片(GS)上直接生长过渡金属磷镍钼化合物。采用扫描电子显微镜(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)等表征手段对所制备电极材料进行表征，并研究了其催化性能。结果表明：所制备的Mo-Ni-P非晶薄膜电极材料薄膜厚度为1~12 μm，表现出优异的催化析氢(HER)和葡萄糖检测性能。以其作为催化析氢电极材料，在阴极电流密度为10 mA·cm-2时，过电位为67 mV，Tafel斜率为667 mV·dec-1。以其作为葡萄糖传感器的电极材料，检测葡萄糖的线性范围为10×10-3~15 mmol·L-1，灵敏度为6 360 μA·cm2·mmol·L-1，检出限为037 μmol·L-1，可排除抗坏血酸(AA)，尿酸(UA)和氯化钠(NaCl)等的干扰，且表现出良好的重复性和稳定性。

Abstract: In this paper, the transition metal phosphorus nickel molybdenum compounds (Mo-Ni-P) were grown directly on the low-cost commercial graphite sheet (GS) via electrochemical deposition method with the aim of developing the electrode materials for high-efficiency hydrogen evolution reaction (HER) and glucose detection. The as-prepared electrode materials were characterized by scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray diffraction (XRD) and X-ray photoelectron spectrometer (XPS), and their catalytic performance was also investigated. The results indicate that Mo-Ni-P amorphous film electrode materials prepared with the film thickness of 1-1.2 μm exhibit excellent HER catalytic activity and glucose detection property. As HER electrode materials, when the cathodic current density is 10 mA·cm-2, the over-potential is 67 mV and the Tafel slope is 66.7 mV·dec-1. As glucose sensor electrode materials, it displays a linear range of 10 ×10-3—1.5 mmol·L-1 towards glucose, a sensitivity of 6 360 μA·cm2·mmol·L-1, a detection limit of 0.37 μmol·L-1. The interference of ascorbic acid (AA), uric acid (UA) and sodium chloride (NaCl) could be excluded, and it exhibits favorable repeatability and stability.
