Facile Synthesis Of Moo3 Nanoplates Based No2 Gas Sensor: Ultra-Selective And Sensitive
CHEMICAL PHYSICS LETTERS(2021)
摘要
Cost effective, simple chemical route has been applied for development of orthorhombic MoO3 for gas sensing application. Opto-structural study confirmed that, the formation of phase pure stable orthorhombic crystal structure with 3.2 eV band gap value. Morphological results reveals the formation of two dimensional nanoplate like surface morphology, which more suitable for gas sensing application. The synthesized MoO3 film is highly selective and 20-fold greater sensitive for detection of NO2 gas in comparison with other gases. As a result, the highest gas sensitivity 71.8% was obtained at 200 degrees C for 100 ppm of NO2 gas. Overall results indicated that, the synthesized material can suitable candidate for sensitive and selective exposure for NO2 gas.
