Morphology Controlled Synthesis of Co3O4 Nanostructures for Hydrazine Chemical Sensor
Herein, we report the successful synthesis of two types of Co3O4 nanostructures, i.e., urchin-shaped and nanoneedle bundles. The prepared nanomaterials were synthesized via facile hydrothermal and subsequent heat treatment process at 300 °C. The structure and morphologies of both prepared materials were thoroughly characterized using different analytical tools and finally, the prepared nanomaterials were used as electron mediators to fabricate high-sensitive hydrazine chemical sensors. The detailed sensing studies revealed that the fabricated sensors based on Co3O4 urchin-shaped and nanoneedle bundles exhibited high sensitivity and low-detection limit. The detailed sensing performances such as sensitivity, detection limit, and linear range for the fabricated hydrazine chemical sensors were comprehensively compared. The results exhibited that the Co3O4 urchin-shaped structures based hydrazine sensor showed wider linear range (5–610 μM) and lower detection limit (1.29 μM), however, the Co3O4 nanoneedle bundles based hydrazine sensor exhibited higher sensitivity (95.25 μA·mM–1).
