XL Space deionizes (removes the phosphates and stannates) all the hydrogen
peroxide he sells.

Moon Express changed from XL peroxide to FMC after having catalyst
poisoning issues running XL. Of course it's always possible that the
contamination came from elsewhere, but there have not been similar
issues with FMC's stuff.
But, as mentioned, FMC is ~86%. So if you want anything higher (or
want to use it on a manned system) either you pay a lot for a large
batch from FMC, go with XL, find another supplier, or start your own
purification. Regardless of the approach, if you are using poisonable
catalyst like silver (not all catalysts can be poisoned) then you
should have the peroxide assayed for impurities.
