Abstract Various copper loaded ZSM-5 zeolites was prepared and characterized in details of their optical, structural, morphological, elemental properties by various conventional methods. The Cu-ZSM-5 zeolites were deposited on silver electrode to result in a chemical sensor that has a fast response to selective 3-methoxyphenol (3-MP) in buffer phase. Analytical sensor parameters such as sensitivity, detection limit, reproducibility, selectivity, repeatability, linear dynamic range, and electrochemical performances were investigated in details with the Cu-ZSM-5 zeolites fabricated sensors. The calibration plot is linear over the large 3-MP concentration range. The sensitivity and detection limit of target 3-MP is calculated as ∼13.232 μA cm−2 μM−1 and 0.083 ± 0.002 nM (at a signal-to-noise-ratio, SNR of 3) respectively. With such excellent features as wide linear dynamic range, higher sensitivity, good stability, lowest detection limit, excellent selectivity, the developed sensor provides a new strategy for determination of 3-MP in biomedical and environmental sample with satisfactory results.

载铜 ZSM-5 沸石：为环境安全开发的超灵敏酚醛传感器

摘要 制备了各种载铜ZSM-5沸石，并通过各种常规方法对其光学、结构、形态、元素性质进行了详细表征。Cu-ZSM-5 沸石沉积在银电极上，形成了一种化学传感器，该传感器对缓冲相中的选择性 3-甲氧基苯酚 (3-MP) 具有快速响应。使用 Cu-ZSM-5 沸石制造的传感器详细研究了分析传感器参数，如灵敏度、检测限、再现性、选择性、重复性、线性动态范围和电化学性能。校准图在较大的 3-MP 浓度范围内呈线性。目标 3-MP 的灵敏度和检测限分别计算为 ~13.232 μA cm-2 μM-1 和 0.083 ± 0.002 nM（信噪比，SNR 为 3）。
