Synthesis and gas sensing properties of amorphous NiTiO3

ABSTRACT: Amorphous NiTiO3
nanoparticles were synthesized using the hydrothermal method. The morphology,
structure, and gas sensing performance of synthesized NiTiO3
samples were investigated. The analysis?s results showed
that the synthesized NiTiO3
has an amorphous phase. The amorphous NiTiO3
has no gas sensitivity to ethanol
(C2H5OH), benzoic acid (C3H6
COOH), or acetone (C3H6O); but it has gas sensitivity to ammonia (NH3
), phenol
(C6H5OH), formaldehyde (HCHO), water vapor (RH85%), and hydrogen peroxide (H2O2
). Due to the anisotropy
of the sample phase, NiTiO3
shows higher sensitivity and faster response for multiple target gas analytes. These results
show that amorphous NiTiO3
can be used to develop gas sensors.
