Zinc oxide nanopyramids modified screen printed electrode for high sensitive and low-concentration sensor application |
| 초록 |
A facile and simple hydrothermal method was used to synthesize the hexagonal zinc oxide nanopyramids (ZnO-NPys) and successfully applied as active materials to modify disposable screen printed electrode (SPE) for detecting the dichloromethane (DCM) chemical. FESEM analysis exhibited a high aspect ratio of hexagonal nanopyramid like structures and the structural studies evidenced that the synthesized materials were well–crystalline with typical wurtzite ZnO crystal. ZnO-NPys modified SPE detected low concentrations of DCM which were measured by a simple cyclovolatmetry (CV) technique. A promising sensitivity of ~293.5 μA/μM/cm-2 with a limit of detection (LOD) of ~17.3 μM, excellent linearity in the range of 100 nM -200 μM and a good retention coefficient (R) of ∼0.982055 were observed. Thus, it is believed that ZnO-NPys could be a promising candidate for the fabrication of efficient sensors for detecting hazardous chemicals. |
