Electrochemical detection of resorcinol chemical using unique cabbage like ZnO nanostructures

Cabbages like zinc oxide nanostructures (C-ZnO NSs) were synthesized by low temperature hydrothermal method and applied as an electrode for the detection of resorcinol chemical via electrochemical sensor. The morphological characterizations revealed that small sheets were arranged into a cabbage like morphology which possessed well-crystalline nature with typical hexagonal wurtzite phase. The FTIR and XPS analysis deduced that the synthesized C-ZnO NSs were of good crystal quality with fewer defects. As 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 were recorded by the synthesized C-ZnO NSs electrode.
