Abstract

The fabrication and characterization of ultra-high sensitive hydrazine chemical sensor based on zinc oxide (ZnO) nanocones are reported. The ZnO nanocones were synthesized by a low-temperature solution process and examined by various techniques in terms of their morphological, structural, compositional and optical properties. The studies revealed that the synthesized ZnO materials possessed good-crystallinity and defined nanocone morphologies and exhibited good optical properties. The hydrazine chemical sensor was fabricated on the amperometric principle and shows ultra-high sensitivity and low detection limit. The estimated sensitivity and detection limit of the fabricated hydrazine chemical sensor were 50×104 µA µM−1 cm−2 and 0.01 µM, respectively. The observed response time was <2 s.
