The porous Ni/β-Ni(OH)2 superstructures have been successfully prepared via a simple, fast one-pot solvothermal route in the presence of cetyltrimethyl ammonium bromide (CTAB), using NiCl2·6H2O and NaBH4 as the original reactants. The reaction was carried out in ethylene glycol at 170°C for 1h. The morphology of the obtained product could be controlled by adjusting the reaction time and the surfactant. The products were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive spectrometry (EDS), Infrared (IR) spectrometry, and Brunauer-Emmett-Teller (BET). The electrochemical property of the as-obtained superstructures was investigated through the cyclic voltammogram (CV) measurements. It was found that the as-obtained porous Ni/β-Ni(OH)2 superstructures exhibited good electrochemical properties and could be used as electrochemical sensors for the detection of some organic small molecules such as hydrochinone, pyrocatechol, and glucose.
多孔 Ni/β-Ni(OH)2 超结构是通过在十六烷基三甲基溴化铵（CTAB）存在下，使用 NiCl2·6H2O 和 NaBH4 作为原始反应物，通过简单、快速的一步溶剂热路线成功制备的。反应在乙二醇中于 170°C 下进行 1 小时。通过调整反应时间和表面活性剂，可以控制所得产物的形态。通过 X 射线粉末衍射（XRD）、扫描电子显微镜（SEM）、透射电子显微镜（TEM）、能谱（EDS）、红外（IR）光谱和 Brunauer-Emmett-Teller（BET）对产物进行了表征。通过循环伏安法（CV）测量研究了所得超结构的电化学性能。结果表明，所得多孔 Ni/β-Ni(OH)2 超结构具有良好的电化学性能，可作为电化学传感器用于检测一些有机小分子，如对苯二酚、邻苯二酚和葡萄糖。
