要:以 ZIF-8 衍生碳材料(ZDC)为载体原位生长锆基 MOF 材料 NH2-UiO-66,制备了一 种 MOF 杂化材料(标记为 ZDC@NH2-UiO-66),利用其对丝网印刷电极进行表面改性,实现 了对铜离子(Cu2+)的简便、灵敏电化学检测。制备的 ZDC@NH2-UiO-66 具有较本体 NH

2- UiO-66 显著改善的导电性和更好的分散性,这促进了电极表面的电化学信号传导,并为 Cu2+ 的富集提供了大的比表面积和丰富的吸附位点。采用 ZDC@NH2-UiO-66 对丝网印刷电极进 行修饰,所制备的 Cu2+ 电化学传感平台显示出宽的线性范围(10~1 000 nmol · L−1 )和高灵 敏度(检出限为 1. 6 nmol · L−1 ),且具有良好的选择性、重现性和稳定性。该研究为 MOF 材 料的性能调控提供了一种新策略,为 Cu2+的简便、快速、灵敏检测提供了一种新平台,在现场、 实时检测痕量 Cu2+方面显示出光明的应用前景。

Abstract:In this paper, a hybrid material labeled as ZDC@NH

2-UiO-66 was prepared by insitu growth of zirconium-based metal-organic framework (MOF) NH2-UiO-66 on ZIF-8 derived carbon material (ZDC), and used for the surface modification of screen-printed elec trode to achieve simple and sensitive electrochemical detection of copper ion (Cu2+). The pre pared ZDC@NH

2-UiO-66 had significantly improved conductivity and better dispersion than

the bulk NH2-UiO-66, which promoted the electrochemical signal conduction on the electrode surface, and provided a large specific surface area and abundant adsorption sites for the enrich ment of Cu2+ . The Cu2+ electrochemical sensing platform based on ZDC@NH2-UiO-66 modi fied screen-printed electrode exhibited a wide linear range (10—1 000 nmol · L-1 ) and high

sensitivity (detection limit of 1. 6 nmol · L-1 ), as well as excellent selectivity, reproducibility, and stability. This study provides a new strategy for the performance regulation of MOF mate rials, supplies a new platform for the simple, rapid and sensitive detection of Cu2+ , and shows a bright application prospect in the field and real-time detection of trace Cu2+.
