A Nanoparticulate Photocatalytic Filter for Removal of Trace Contaminant Gases, Phase I

Maintaining a healthy atmosphere in closed life support systems is necessary for the well being of the crew and success of a space mission. Current trace contaminant control systems for removal of trace contaminant gases from cabin air are based on activated carbon filter and high temperature catalytic oxidation. However, activated carbon and high temperature oxidation air cleaners suffer from absorbent saturation and poisoning, which leads to off gassing. Also, the units become a breading ground for microorganisms, and the activated carbon generates a potentially hazardous secondary waste stream. In this Phase I project Lynntech proposes to demonstrate the feasibility of using a reagentless advanced low temperature catalytic air-revitalizing unit based on a nanoparticulate photocatalytic filter to eliminate both chemicals and microorganisms from air. The benefits of this approach are its low cost, low power consumption, longevity, diverse flow rate capacity, size and performance. In addition, it is reagentless and it does not generate a secondary waste stream. In the Phase II project, a fully operational prototype will be delivered to NASA.

This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
