Uranium catalyzed electrolysis of water to produce hydrogen.

2. Note this reaction is carried out in THF, obviously...

...wet THF.

Early in my career I spent a lot of time trying to dry THF; although one can form separable phases with aqueous solutions, THF in a biphasic system will contain a lot of water. One can see this easily by dropping sodium metal into wet THF. In fact, in periods of extreme laziness, when working late in the lab, it's how I used to get rid of excess sodium, since I often had a lot of wet THF laying around. It probably was dangerous to do that, but I was a kid, and what do kids know?

In theory, this catalyst system is a means to dry THF. It may beat the hell out of distilling out over phosphorous pentoxide.

I'm not sure what effect this chemistry might have on the formation of peroxides though. It probably wouldn't be pretty, although the redox system overall might well minimize that problem. I don't know. These scientists didn't blow up, and lived to publish, a good thing, I think.
