Cheap Metal Catalyst Makes Hydrogen from Water

This sounds quite interesting & encouraging,

molybdenum-oxo metal complex that is about
70 times cheaper than platinum
. . .
does not require organic additives, and can operate in neutral water, even if it is dirty, and can operate in sea water, the most abundant source of hydrogen on earth and a natural electrolyte. These qualities make our catalyst ideal for renewable energy and sustainable chemistry."
. . .
the research team found that this complex catalyzes the generation of hydrogen from neutral buffered water or even sea water with a
turnover frequency of 2.4 moles of hydrogen per mole of catalyst per second.

cranking out 5 grams of H2 per second per mole [unknown grams, maybe 50 grams?] of catalyst sounds like a pretty good production rate to me.

My question is, if it is splitting water, what is it doing with the oxygen?
Making O2 [air oxygen]? O3 [ozone]?
How does one keep oxygen out of the same place the hydrogen goes so it doesn't re-react [explode/burn]?

From reading the article it would appear that this new catalyts replaces that platinum in a conventional electrolysis model. So O2 and H2 are generated at the positive and negative electrodes respectively.

At 70 times cheaper than platinum this tech could be a huge breakthrough literally earth changing well worth a WOW.

That would be a revolutionary breakthrough, if it can be carried out on an industrial scale.

Good find! But it still requires a lot of electricity.
