In this study we demonstrate a new composite oxide thin films of (MoO 3)1 - x(V2O5)x, x = 0, 0.01, 0.03, and 0.05, fabricated by pulsed laser deposition (PLD). The performance of platinum (Pt) catalyst activated hydrogen gas sensor with modified (MoO3)1 - x(V2O5) x thin films were investigated. The thickness of the (MoO 3)1 - x(V2O5)x thin film is about 600-650 nm and its surface has a uniform morphology. Our results show that the gasochromic sensors prepared by (MoO3)0.99(V 2O5)0.01 thin film exhibited excellent hydrogen sensibility. The response and recovery time are in the range of 9-15 min for coloration and bleaching at room temperature under H2 atmosphere. The results also show that (MoO3)1 - x(V2O 5)x/Pt (x = 0.01, 0.03, 0.05) thin films perform better gasochromic capability than the pristine MoO3/Pt sample.
