Hydrothermal synthesis of nanostructured titanium disulfide (TiS2) for detection of NO2 gas and its characterization study
In the present work, A transition metal dichalcogenide (Titanium disulfide (TiS 2 )) has been synthesized by hydrothermal method with Titanium tetra isopropoxide (Ti (OCH (CH 3 ) 2 ) 4 ) as a source of Titanium (Ti) and Thiourea (NH 2 ·CS·NH 2 ) as a source of Sulphur (S) at varying concentrations....

| Summary: | In the present work, A transition metal dichalcogenide (Titanium disulfide (TiS
2
)) has been synthesized by hydrothermal method with Titanium tetra isopropoxide (Ti (OCH (CH
3
)
2
)
4
) as a source of Titanium (Ti) and Thiourea (NH
2
·CS·NH
2
) as a source of Sulphur (S) at varying concentrations. The thick films of nano Titanium disulfide (TiS
2
) were fabricated by using a screen-printing technique. The structural properties of nanostructured TiS
2
were studied by X-ray diffraction (XRD). The XRD data confirm the hexagonal structure of nanostructured TiS
2
and the crystallite size was observed at 23 nm. Scanning electron microscopy (SEM) was used to analyze the morphological properties of the thick film of nanostructured TiS
2
that formed to determine the material's surface properties. The size of the TiS
2
nanoparticles was determined by transmission electron microscopy (TEM). The chemical composition of synthesized material was detected by energy dispersive spectroscopy analysis (EDAX). The prepared TiS
2
thick films were tested for various toxic gases such as Nitrogen dioxide (NO
2
), Hydrogen sulfide (H
2
S), Carbon dioxide (CO
2
), Ammonia (NH
3
), Liquefied petroleum gas (LPG), Ethanol (C
2
H
6
O) and Methanol (CH
3
OH) gases at different gases concentrations and different operating temperatures. The TiS
2
thick film sensor shows the highest sensitivity to NO
2
gas as compared to the other gases at an operating temperature of 160 °C with 600 ppm gas concentration. The prepared TiS
2
thick film sensor shows a rapid response and recovery time. |
