Abstract

A new ZnO/MXene material was made using a simple hydrothermal method and heat treatment for measuring glucose without enzymes in sports drinks and human blood samples. The best ZnO/MXene-300 material, made at 150 °C and heated at 300 °C, had a large surface area of 152 m2/g, high current density of 1.12 mA/cm2, and low activation energy of 32.6 kJ/mol for glucose oxidation. The sensor could measure a wide range of glucose levels (0.01-12 mM) with a low detection limit (0.005 µM), worked well in the presence of other substances, remained stable (93.6% after 7 days), and gave consistent results (RSD of 3.2%). The material was tested by measuring glucose in sports drinks and blood samples, with measured values close to the actual values (96.4–104.5%) and high precision (RSDs of 2.8% and 3.8%). These results show that ZnO/MXene materials are promising for making sensitive and stable glucose sensors that don’t need enzymes.

使用 Mxene/ZnO 复合材料对运动饮料和血清中的葡萄糖进行电催化感应

利用简单的水热法和热处理制成了一种新型氧化锌/氧化铝材料，用于测量运动饮料和人体血液样本中的葡萄糖（不含酶）。最佳的 ZnO/MXene-300 材料在 150 °C 制成并在 300 °C 下加热，具有 152 m2/g 的大表面积、1.12 mA/cm2 的高电流密度和 32.6 kJ/mol 的低葡萄糖氧化活化能。该传感器可测量的葡萄糖浓度范围很广（0.01-12 mM），检测限很低（0.005 µM），在有其他物质存在的情况下也能很好地工作，7 天后仍保持稳定（93.6%），并且结果一致（RSD 为 3.2%）。该材料通过测量运动饮料和血液样本中的葡萄糖进行了测试，测量值接近实际值（96.4-104.5%），精度高（RSD 为 2.8% 和 3.8%）。这些结果表明，ZnO/MXene 材料有望用于制造不需要酶的灵敏、稳定的葡萄糖传感器。

期刊介绍： Topics in Catalysis publishes topical collections in all fields of catalysis which are composed only of invited articles from leading authors. The journal documents today’s emerging and critical trends in all branches of catalysis. Each themed issue is organized by renowned Guest Editors in collaboration with the Editors-in-Chief. Proposals for new topics are welcome and should be submitted directly to the Editors-in-Chief. The publication of individual uninvited original research articles can be sent to our sister journal Catalysis Letters. This journal aims for rapid publication of high-impact original research articles in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis.
