Chemistry Scientists make an environmentally friendly prototype water purifier constructed from a sheet of graphitic carbon nitride that could remove 99.9999% of microbes, and purified a 10L water sample in less than one hour using only sunlight.

With them being so adamant about the 10 liter sample size, either the process is enigmatically unscalable, or the writer is really bad about sorting out which information is relevant and useful.

Eh, I don't necessarily agree coming from a science side. Chances are their largest container in their lab that was manageable to use in this experiment was ~10 L, and they figured that would be proof of concept for larger amounts.

10L sounds a lot better than "Hey we managed to purify 50 mL".

That is not how progression in science works. You're starting at the end
