Cabbage-like ZnO nanostructures for the electrochemical detection of resorcinol

Cabbages like zinc oxide nanostructures (C-ZnO NSs) are synthesized by a low temperature hydrothermal method and applied as an electrode for the detection of resorcinol chemicals via an electrochemical sensor. The morphological characterizations reveal that small sheets are arranged into a cabbage-like morphology, which possess the well-crystalline nature with a typical hexagonal wurtzite phase. The FTIR and XPS analyses deduce that the synthesized C-ZnO NSs are of good crystal quality with fewer defects. As a working electrode, the reasonable sensitivity of ~1.98 µA.µM-1.cm-2 with the detection limit of ~5.89 µM and correlation coefficient (R) of ~0.9766 are recorded by the synthesized C-ZnO NSs electrode.
