Hydrogen Sorbers and Hydrogen Getters

We offer three solutions for hydrogen removal: Irreversible, organic-based hydrogen getters, reversible Pd-coated metal-hydrogen sorbers, and Pt-CeO catalysts. 1) Pd-organic hydrogen getters provide irreversible hydrogen removal from air or steam at 0 to 50°C. Composed of DEB, buckminsterfullerene, and palladium catalyst, the typical use is consumer electronics.
2) Pd-coated metal-hydrogen sorbers provide reversible hydrogen removal from vacuum or inert atmospheres at 20°C to 400°C. Composed of Pd-coated niobium, vanadium, or LaNi5, these sorbers are available in wire, granule, and screw shapes.
3) Pt-CeO catalyst sorbers provide indefinite, irreversible hydrogen removal from air or contaminated gas streams at 0 to 600°C. They can be used without air, and are not readily poisoned by organic and chloride contaminants. Contains 1% Pt to catalyze the reaction H2 + 1/2 O2 --> H2O in air, or the reaction H2 + Ce2O3 --> 2 CeO + H2O. These catalysts are available as pellets or coated screen.


Sorbers

Pd-organic hydrogen sorber. Contains DEB and buckminsterfullerene. For irreversible hydrogen removal from air, nitrogen, or steam at 0 C - 50 C. Typical uses include hydrogen removal from electronic pacages, consumer, and industrial products. They allow safe use of sealed, battery-operated flashlights, divelights, toys, and cameras without the risk of hydrogen detonation.

$350/5 gms.

Pt-CeO hydrogen removal catalyst sorber. Best used in air, but can be used in nitrogen or inert gases as well at 0C to 400 C. Removes hydrogen or oxygen from a gas by converting it to water. Suggested uses include H2 removal inside nuclear waste shipping containers.

$350/5 gms.

Pd-coated niobium screws (4/40). Used to extract hydrogen from inert gas in space-based electronic packages at 25 to 250 C. Pd coated LaNi5 can be very effective in nickel metal hydride batteries or hydrogen storage. Hydrogen sorption is readily reversible.
