摘要：

In this study we demonstrate a new composite oxide thin films of (MoO3)(1-x)(V2O5)(x), x=0, 0.01, 0.03, and 0.05, fabricated by pulsed laser deposition (PLO). 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 (MoO3)(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)(V2O5)(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 H-2 atmosphere. The results also show that (MoO3)(1-x)(V2O5)(x)/Pt (x=0.01, 0.03, 0.05) thin films perform better gasochromic capability than the pristine MoO3/Pt sample. (C) 2010 Elsevier B.V. All rights reserved.
