Method and Pd/V2 O5 device for H2 detection
First Claim
1. An improved method of chemochromic detection of hydrogen gas over a wide range that exhibits stability during repeated coloring/bleaching cycles upon exposure and removal of hydrogen gas, comprising:
- subjecting a sensor structure comprising a substrate, a layer of V2O5 coated on said substrate, and about a 30 nm layer of palladium (Pd) coated on said layer of V2O5 to an environmentcomprising hydrogen to cause a reaction governed by the equation;

Abstract
Methods and Pd/V2O5 devices for hydrogen detection are disclosed. An exemplary method of preparing an improved sensor for chemochromic detection of hydrogen gas over a wide response range exhibits stability during repeated coloring/bleaching cycles upon exposure and removal of hydrogen gas. The method may include providing a substrate. The method may also include depositing a V205 layer that functions as a H2 insertion host in a Pd/V205 hydrogen sensor to be formed on said substrate. The method may also include depositing a Pd layer onto said V205 layer; said Pd layer functioning as an optical modulator.
