I'm wondering: can a "blue TiO2 nanotube array" anode make perchlorate?

This type of anode is described in this paper:

Seems interesting and replicable in amateur setting given some commitment. If I get my hands on a sample of ammonium fluoride then I'll give it a try.

Nice find, looks really interesting indeed. I'm tempted to try it too, but it will have to wait until I can find time for experiments again.

I wander if NaF can be substituted.
They also mention adding ethylene glycol to that same electrolyte, but don't specify the concentration or amount to add. Maybe it is described in reference [25], but the full text for ref 25 sits behind a paywall.

Blue TiO2 NTA might also make a good field emission cathode.

And I see that someone is selling ammonium fluoride on amazon at a price of $25 for 150 grams.

(BTW from another paper it seems that this stuff may eventually lose catalytic activity as Ti3+ is slowly oxidized to Ti4+ but it can apparently be largely restored by periodic cathodic polarization).

If anyone tries making this please post your progress/results here.

(This topic is waaayy outside my knowledge, but I figured providing the paper could be more helpful than nothing)
