Abstract: The present invention relates to a textile composite for the adsorption and breakdown of harmful chemical materials. A support layer and a sorptive and reactive material mounted on the support layer form a protective layer, which is mounted on an inner liner. The protective layer adsorbs and breaks down harmful chemical materials. An outer shell is formed of fabric having an outer surface that is hydrophobic for resisting the passage of harmful chemicals, which may be in the form of vapor, liquid or aerosols. Preferably, the sorptive and reactive material includes zirconium hydroxide, and the support layer includes a fabric material. The zirconium hydroxide is distributed on the fabric material in the amount of at least 20 grams of zirconium hydroxide per square meter. Alternatively, the zirconium hydroxide is distributed in the amount of at least 150 or 200 grams of zirconium hydroxide per square meter.

Abstract: A method of making a membrane permeable to hydrogen gas (H2?) is disclosed. The membrane is made by forming a palladium layer, depositing a layer of copper on the palladium layer, and galvanically displacing a portion of the copper with palladium. The membrane has improved resistance to poisoning by H2S compared to a palladium membrane. The membrane also has increased permeance of hydrogen gas compared to palladium-copper alloys. The membrane can be annealed at a lower temperature for a shorter amount of time.
