作者描述了一种以低成本生物质冬瓜(Benincasa hispida)为原料合成三维(3D)互连碳纳米棒气凝胶(3D-ICNA)的方法。 3D-ICNA 具有独特的 3D 互连多孔纳米结构,具有丰富的边缘平面状缺陷位点、大的比表面积 (823 m2g−1) 和大的孔体积 (0.12 cm3g−1)。这使得该材料在电化学传感方面具有吸引力。为了验证可行性,使用经过 3D-ICNA 修饰的玻碳电极 (GCE) 研究了对铁氰化物、过氧化氢 (H2O2)、对乙酰氨基酚、抗坏血酸 (AA)、多巴胺、尿酸和肾上腺素的伏安响应。改进后的 GCE 显示出比传统 GCE 更高的电子转移能力。此外,作为AA或H2O2的电化学传感器,该电极表现出更好的分析性能,具有较低的检测限[基于3σ/m标准,AA为3.5μM,H2O2为0.68μM(其中σ是空白的标准差,是校准图的斜率)],更宽的线性范围和更高的灵敏度(0.14、0.11和0.080μAμM−1cm−2) AA 或 0.24 和 0.20 µA µM−1cm−2(对于 H2O2))与普通 GCE 或碳纳米管改性 GCE 相比。改进的GCE在实际样品中AA或H2O2的电流分析中表现出巨大的潜力。图文摘要以冬瓜(Benincasa hispida)生物质为前驱体,制备了三维互连碳纳米棒气凝胶。它被证明是构建先进的 H2O2 和抗坏血酸电化学传感器的可行材料。
The authors describe a method for synthesis of a three-dimensional (3D) interconnected carbon nanorod aerogel (3D-ICNA) starting from wax gourd (Benincasa hispida) which is a low-cost biomass. The 3D-ICNA possesses unique 3D interconnected and porous nanostructure, with abundant edge-plane-like defective sites, a large specific surface area (823 m2g−1) and a large pore volume (0.12 cm3g−1). This makes the material attractive in terms of electrochemical sensing. To validate the feasibility, the voltammetric response towards ferricyanide, hydrogen peroxide (H2O2), acetaminophen, ascorbic acid (AA), dopamine, uric acid and epinephrine was investigated by using a glassy carbon electrode (GCE) modified with 3D-ICNA. The modified GCE shows higher electron-transfer capacity than a conventional GCE. In addition, as an electrochemical sensor for AA or H2O2, the electrode exhibits better analytical performance with lower detection limit [3.5 μM for AA or 0.68 μM for H2O2based on 3σ/m criterion (whereσis the standard deviation of the blank andmis the slope of the calibration plot)], wider linear range and higher sensitivity (0.14, 0.11 and 0.080 μA μM−1cm−2for AA or 0.24 and 0.20 μA μM−1cm−2for H2O2) compared to a plain GCE or a carbon nanotube-modified GCE. The modified GCE exhibits a large potential for the amperometric determination of AA or H2O2in real samples.Graphical abstractBy employing the biomass of wax gourd (Benincasa hispida) as the precursor, a three-dimensional interconnected carbon nanorod aerogel was prepared. It is shown to be a viable material for the construction of an advanced electrochemical sensor for H2O2and ascorbic acid.
