High-performance electrochemical sensor based on Pt-Ag@Cu-BDC MOF composite modified glassy carbon electrode for detection of imidacloprid in citrus juice and water samples.

ABSTRACT: The key factor to improve the sensitivity of electrochemical sensors for direct detection, is the introduction of new nanomaterials with enhanced catalytic properties. Accordingly, we prepared Pt-Ag@Cu-metal organic framework (MOF) as a novel nanocomposite to construct a sensitive electrochemical sensor for voltammetric determination of imidacloprid (IMI). The copper benzene-1,4-dicarboxylate framework (Cu-BDC MOF) was used as support for bearing the metal nanoparticles (NPs) including Ag and Pt. First, Ag NPs were incorporated into Cu-BDC MOF and then Pt NPs were substitute through galvanic replacement reaction between Ag NPs and Pt ions. The Pt-Ag@Cu-BDC MOF as a novel nanocomposite was utilized as a modifier to decorate glassy carbon (GC) electrode. The excellent conductivity, hierarchi
