Amorphous MoS2 thin films have been prepared by thermal deposition on glass, quartz, and FTO substrates and investigated by UV-VIS -NIR spectroscopy. The type of substrate has a minor impact on the film's spectral absorption and band gap values. The investigation of MBdye degradation by MoS2 catalyst under UVirradiation demonstrates high efficiency of 86%. MoS2 films deposited on glass substrates have been experienced as CO2, HCl, and I2 gas sensors. The films revealed promises for CO2 sensing at high temperatures (T≥300℃) in terms of relatively good response (~ 3 min) and moderate recovery of ~12 min. Besides, MoS2 films revealed a quick response within 1 min for both HCl and I2 gases, while their entire recovery needs a time period longer than one hour.
