O2 Scrubbing? Answered

Looking at what media i need to scrub out O2 from the atmosphere. My research is yielding little but what i have found is that Copper Oxide and Aluminum Oxide will do the job apparently, though i'm unsure. Thoughts?

you want to remove O2?

Canned food used to include some nails. The nails would rust, preventing the can from rusting out from the inside.

Like a toy in a cereal box: a great surprise!

For your needs, damp steel wool may work.

You need to learn how to use Google properly - no offense!
CO2 scrubber as used for rebreathers in diving give you the basic working priciple with all the details you need - it makes no difference what gas you want to remove for the apparatus in use ;)
Now take a look at fancy foods and for example in beef jerky you find small packs that upon reading reveal to remove oxygen for the inside of the packing.
A quick Google check confirms that often very fine iron dust is used with a "binder" so it won't go through the fine holes.
You don't use oxides if you want to remove oxygen - you oxidise to remove oxygen ;)
You did not say if you only need to remove O2 or if you can tolerate some other gas to replace it?
Asking as a simple flame will remove oxygen quite good....

If you have not already tried asking this to Google,

https://www.google.com/#q=removing+oxygen+from+air

The first link is to a Wikipedia article titled, "Air separation"

https://en.wikipedia.org/wiki/Air_separation

I mean that will tell you how the pros do it.

Although for something like this, I might want to see if that question has been asked at "site:sciencemadness.org", because if someone knew how to do this at home, with simple equipment, in the garage or backyard, it would likely be one of the people who post there.

Also there exists a commercial product I have heard of, and seen, usually in the form of little packets, intended for removing the oxygen in a container of stored food. I have heard them called, "oxygen absorbers". The Wikipedia article title for the same, calls them, "oxygen scavengers". I think they work via some kind of reaction with finely divided, powdered iron.

AlO2 has a very firm grip on its oxygen. Pure clean Aluminium will absorb oxygen very readily though when heated.

Why do you want to remove the oxygen?

As an example; in welding they block the oxygen with am inert gas to weld aluminum.
