Abstract

A method is presented in this paper for treating NiCo₂O₄ nanostructures with boric acid in an environmentally friendly and cost-effective manner. Boric acid was applied to chemically prepared NiCo₂O₄ nanostructures for different periods of time, including 30, 60, and 120 min. A variety of analytical techniques were used to examine the morphology, crystallinity, functional groups, and optical band gaps of the crystals. This resulted in the development of an electrochemical non-enzymatic ascorbic acid sensor using NiCo₂O₄ nanostructures treated with boric acid. After being infused with 0.5 M boric acid for 120 min, NiCo₂O₄ nanostructures demonstrated excellent performance for oxidizing AA in a phosphate buffer solution of pH 7.4. There was a wide linear range for non-enzymatic detection between 0.1 and 20 mM. We determined a limit of detection of approximately 0.003 mM and a limit of quantification of approximately 0.008 mM.

用硼酸化学处理镍钴氧化物纳米结构以开发用于非酶促性抗坏血酸传感器的高性能电催化材料

本文介绍了一种用硼酸处理镍钴氧化物纳米结构的方法，该方法既环保又经济。将硼酸应用于化学制备的镍钴氧化物纳米结构中，时间分别为 30、60 和 120 分钟。使用了多种分析技术来检测晶体的形态、结晶度、官能团和光学带隙。最终，利用硼酸处理过的镍钴氧化物纳米结构开发出了一种电化学非酶抗坏血酸传感器。用 0.5 M 硼酸浸泡 120 分钟后，NiCo2O4 纳米结构在 pH 值为 7.4 的磷酸盐缓冲溶液中氧化 AA 方面表现出优异的性能。非酶检测的线性范围很宽，在 0.1 至 20 mM 之间。我们测定的检出限约为 0.003 mM，定量限约为 0.008 mM。
