Methods and Pd/VOdevices 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 V0layer that functions as a Hinsertion host in a Pd/V0hydrogen sensor to be formed on said substrate. The method may also include depositing a Pd layer onto said V0layer; said Pd layer functioning as an optical modulator.

Method and Pd/V2 O5 device for H2 detection

Photo-oxidation catalysts and methods for cleaning a metal-based catalyst are disclosed. An exemplary catalyst system implementing a photo-oxidation catalyst may comprise a metal-based catalyst, and a photo-oxidation catalyst for cleaning the metal-based catalyst in the presence of light. The exposure to light enables the photo-oxidation catalyst to substantially oxidize absorbed contaminants and reduce accumulation of the contaminants on the metal-based catalyst. Applications are also disclosed.

Photo-oxidation catalysts

A sensor structure for chemochromic optical detection of hydrogen gas over a wide response range, that exhibits stability during repeated coloring/bleaching cycles upon exposure and removal of hydrogen gas, comprising: a glass substrate (); a vanadium oxide layer () coated on the glass substrate; and a palladium layer () coated on the vanadium oxide layer.
