Another point, working with NH3/O2 or H2O2 is, in my assessment, not a basic piranha reaction, actually electrochemical (and a bit more) in nature.
See related chemistry with copper, ammonia and O2 (or H2O2) at https://www.sciencemadness.org/whisper/viewthread.php?tid=15... and elsewhere on this forum.
Implication of this point is adding NH4Cl (or the sulfate) likely improves the reaction rate as in the case of copper.
