I'm pretty sure that Hydrogen Peroxide or Bleach can kill the coronavirus at their usual disinfecting concentrations in a glass tube but reaching those concentrations in a human would most probably kill him because oxidants like those damage tissue, not only viruses.
There were claims that breathing Ozone (another oxidant) at small concentrations was 'helpful' for protecting medical workers from the virus but those claims did not get any development - most probably because they don't work. Ozone is also damaging at higher concentrations.
