文摘
- •
Resistive gas sensors based on Zn/Al-LDHs are fabricated by hydrothermal growth on interdigitated fingers array.
- •
LDHs sensing layer is characterized by Scanning Electron Microscopy, X-Ray Diffraction and Energy-Dispersive X-Ray Spectroscopy.
- •
Gas sensors are tested in the detection of five volatile compounds (CO, CO2, NO, NO2 and CH4) at six concentration.
- •
Sensor characteristics of LDHs layer (Selectivity, Sensor Response, Sensitivity, etc.) are estimated.
