摘要：

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 x 10(4) mu A mu M-1 cm(-2) and 0.01 mu M, respectively. The observed response time was < 2 S.
