Template assisted Synthesis of tin oxide nanostructures electrodes by using nanoporous alumina template for detection of toxic chemicals in water such as hydrazine

Abstract

Template-assist method is one of the most important techniques for synthesize nanostructures , because of more parameters that can be change to fabricate different nanostructures with desired nano-scale features. self- ordered anodic alumina is one of the most important honeycomb structure that can be used as a template. by using self-ordered nanoporous as a template and hydrothemal process as a deposition technique,different structures like nanowire,nanotube and nanoparticle was fabricated. The effect of surfactant and temperature on the formation of various nano-structures were investigated by SEM (scanning electron microscopy) and EDX (Energy dispersive x- ray) analysis. Electrical properties and I(Current)- Voltage (V)- Gate - source behavior of the samples was measured by four-probe (4- probes) method. Tin oxide nanoparticle array on the surface of alumina membrane used as chemical sensor in case of detecting hydrazine. The obtained results indicate that Alumina doped with tin oxide nanoparticle is suitable for detection of toxic chemicals in water such as hydrazine.
