A novel sensor based on Ag-loaded zeolitic imidazolate framework-8 nanocrystals for efficient electrocatalytic oxidation and trace level detection of hydrazine

- ZIF-8 nanocrystals were synthesized using a simple room temperature method.
- For the first time, Ag-loaded ZIF-8 nanocrystals were used to detect hydrazine.
- Ag/ZIF-8/CPE shows good catalytic performance toward hydrazine oxidation.
- Ag/ZIF-8/CPE has rapid response time, wide linear range and low detection limit.
- The sensor is selective and practical feasible toward the detection of hydrazine.
