Metal–organic frameworks (MOFs) are the more desirable electrode materials in the recent development of electrocatalyts. Still, the electrocatalytic behavior as well as the stability of the prepared MOFs were diminished by its poor conductance. In this work, Cobalt hydroxide (Co (OH)₂) functionalized multi-walled carbon nanotubes (MWCNTs) with enhanced electro activity has been prepared using Co-based metal−organic framework (Co MOF, ZIF-67) templates through room temperature electrochemical synthesis. The as synthesized composite has been utilized in the construction of MWCNTs-Co(OH)₂ modified glassy carbon electrode (GCE) for the determination of hydrazine (N₂H₄) and hydrogen peroxide (H₂O₂). The higher electrochemical performance of MWCNTs-Co(OH)₂/GCE compared to individual MWCNTs/GCE and Co(OH)₂/GCE was evident from the cyclic voltammetric studies. The characterizations of the composite have been carried out using various techniques. The electrochemical parameters such as linear range, limits of detection and sensitivity of MWCNTs-Co(OH)₂/GCE were found to be more comparable with the previous N₂H₄ and H₂O₂ amperometric sensors reported in the literatures. The outcomes of practicability inspections were adequate with the recovery results of conventional methods. The high selectivity of MWCNTs-Co(OH)₂ modified GCE towards N₂H₄ and H₂O₂ has been further demonstrated in the presence of several biologically interfering molecules.

在最近的电催化剂开发中，金属有机骨架（MOF）是更理想的电极材料。仍然，制备的MOF的电催化行为以及稳定性由于其差的电导性而降低。在这项工作中，已通过室温电化学方法使用基于钴的金属有机骨架（Co MOF，ZIF-67）模板制备了具有增强的电活性的氢氧化钴（Co（OH）₂）功能化的多壁碳纳米管（MWCNT）。合成。所合成的复合物已用于MWCNTs-Co（OH）₂修饰的玻碳电极（GCE）的结构中，用于测定肼（N ₂ H ₄）和过氧化氢（H ₂ O _2））。从循环伏安法研究中可以看出，与单个MWCNTs / GCE和Co（OH）₂ / GCE相比，MWCNTs-Co（OH）₂ / GCE的电化学性能更高。复合材料的表征已使用多种技术进行。发现电化学参数如线性范围，MWCNTs-Co（OH）₂ / GCE的检测限和灵敏度与文献中报道的先前的N ₂ H ₄和H ₂ O ₂电流传感器更具有可比性。实用性检查的结果与传统方法的恢复结果相比是足够的。MWCNTs-Co（OH）₂的高选择性在几种生物干扰分子的存在下，已进一步证明了针对N ₂ H ₄和H ₂ O _2的修饰的GCE 。
