HIGH SENSITIVITY PHENYL HYDRAZINE SENSOR BASED ON HIGHLY ALIGNED TITANIUM DIOXIDE NANOTUBE ELECTRODE

摘要

The present invention relates to a high sensitivity phenyl hydrazine sensor based on a highly aligned titanium dioxide (TiO_2) nanotube electrode, more specifically, to a high sensitivity phenyl hydrazine sensor based on a TiO_2 nanotube array electrode. The high sensitivity phenyl hydrazine sensor based on a TiO_2 nanotube array electrode is formed by a method comprising: a step of degreasing a titanium (Ti) foil in a ultrasonic cleaner to wash the Ti foil using distilled water, and then drying the Ti foil; a step of electrochemically anodizing the Ti foil in two electrode battery systems including ammonium fluoride dissolved in an ethylene glycol solution and purified water; and a step of cleaning a TiO_2 nanotube array grown on the anodized Ti foil using distilled water and sintering the TiO_2 nanotube array. The chemical sensor based on a highly aligned TiO_2 nanotube electrode has high sensitivity and is safe since an extremely small amount can be measured in short reaction time.;COPYRIGHT KIPO 2016
