Abstract:
Novel, hierarchically nanostructured, star‐shaped ZnO (SSZ) microparticles are synthesized by a hydrothermal synthetic route. The SSZ microparticles serve as effective platforms for electrochemical detection of amines in solution. The morphology and structure of the materials are characterized by X‐ray diffraction, scanning electron microscopy, transmission electron microscopy, Raman spectroscopy, and UV/Vis spectroscopy. The as‐synthesized SSZ microparticles comprise self‐assembled hexagonal prisms that possess nanometer and micrometer pores in their structure and on their surfaces—structural features that are conducive to sensing applications. An electrode fabricated by using the hierarchically nanostructured SSZ materials serve as a sensitive electrochemical sensor for detection of low concentrations of ethylenediamine, with a sensitivity of 2.98×10 −2 mA cm −2 m m −1 , a detection limit of 2.36×10 −2 m m , and a short response time of 8 s.
