The present manuscript describes the formation of oxide based nanocomposite of copper and iron oxide (CuFeO₂NCNPs) nanoparticles. The nanocomposite nanoparticles (NCNPs) were processed via solution process with copper nitrate hexahydrate, iron nitrate nonhydrate and sodium hydroxide as a reducing agent. The chemicals were utilized to form a uniform solution and it refluxed at ∼80 °C for 60 min for the formation of CuFeO₂NCNPs and analyzed well with various techniques. It reveals that the NCNPs are in range of 45–50 nm in size with clear spherical shaped morphology with good chemical characteristics. These NCNPs were utilized for to check their sensing performance against phenol, which is a hazardous chemical compound for the environment and human body analysed with glassy carbon electrode (GCE). The electrochemical observations were conducted with cyclic voltammetry (CV) from very low to high concentration range (7.8 μM–1000 μM in PBS) of phenol; effect of scan was analyzed from 5 to 100 mV/s with CuFeO₂NCNPs/GCE electrode. The modified sensors reproducibly and sustainability were also identified for a longer period in presence of Phenol (62.5 μM). Based on the results and their discussion a possible mechanism was also presented.

本手稿描述了基于氧化物的铜和铁氧化物 (CuFeO ₂ NCNPs) 纳米颗粒的纳米复合材料的形成。纳米复合纳米粒子 (NCNPs) 采用溶液法处理，其中硝酸铜六水合物、硝酸铁非水合物和氢氧化钠作为还原剂。这些化学物质被用来形成均匀的溶液，并在~80°C 下回流 60 分钟以形成 CuFeO ₂NCNPs 并使用各种技术进行了很好的分析。结果表明，NCNPs的尺寸在45-50 nm范围内，具有清晰的球形形态和良好的化学特性。这些 NCNP 用于检查其对苯酚的传感性能，苯酚是一种对环境和人体有害的化合物，用玻碳电极(GCE) 分析。电化学观察采用循环伏安法 (CV) 从苯酚的极低浓度到高浓度范围（PBS 中 7.8 μM–1000 μM）进行；_{使用 CuFeO 2}从 5 到 100 mV/s 分析扫描效果NCNPs/GCE 电极。在苯酚 (62.5 μM) 存在的情况下，修改后的传感器的可重复性和可持续性也得到了较长时间的鉴定。基于结果和他们的讨论，还提出了一种可能的机制。
