在NiCl 2溶液中，通过阳极氧化金100 s，一步制备了Ni（OH）2/纳米多孔金（NPG）复合电极。由于合成方法的性质，所制备的电极是自支撑的。在最佳条件下，在0.2 μM ~ 1.1 mM范围内，该传感器的灵敏度为3286.1 μA mM−1cm−2，检测限为170 nM，响应时间< 2 s。所提供的策略适用于大多数实验室制备过渡金属氢氧化物（MOHx（M = Ni、Co、Cu、Fe等））。修改后的NPG
A Ni(OH)2/nanoporous gold (NPG) hybrid electrode was one-step obtained by anodizing gold in NiCl2solution for 100 s. The as-prepared electrode is self-supported due to the nature of the synthesis method. Under the optimal condition, it showed an ultrahigh sensitivity (3286.1 μA mM−1cm−2) in a linear range from 0.2 μM to 1.1 mM, a low detection limit (170 nM) and a fast response time (< 2 s) towards nonenzymatic glucose detection in NaOH solution. The provided strategy is applicable in most laboratories to prepared transition metal hydroxide (MOHx(M = Ni, Co, Cu, Fe, etc.)) modified NPG.
