The authors describe a selective hydrazine sensor
that is based on the use of a film of TiO2 nanoparticles faceted
predominantly at the 101 and 001 sides. The hydrazine (Hyd)
sensor was fabricated by depositing the nanoparticles in 5%
concentration in a nafion matrix on a glassy carbon electrode
(GCE). The sensor exhibits a fast response, excellent sensitivity
and good selectivity over 1.0 nM to 10.0 mM. The sensor
responds linearly to the logarithm of the concentration of dissolved
hydrazine in the range from 1.0 nM to 10.0 mM, with a
sensitivity of 35.04 μA.mM−1
.cm−2
. The detection limit is
28.8 ± 0.2 pM (at an S/N ratio of 3) is extremely low. In our
perception, this approach emerges as an effective technique
for developing efficient chemical sensors for environmental
pollutants. [-]
