Hydrogen Peroxide as reducing agent - HELP!

[rnti5]

hello I need help please.

I want to conduct Platinum precipitation experiment and I want to use H₂O₂ instead of ammonium chloride.
PtCl₆^2- + 2 H₂O₂ = Pt + 4 H⁺ + 6 Cl^- + 2 O₂
H₂PtCl₆ + 2 H₂O₂ = 6 HCl + 2 O₂ + Pt

These are the current reactions I am dealing with. In the case where H₂O₂ is acting as a reducting agent instead of oxidation agent.
Does anyone has experience in using hydrogen peroxide in cases like this. I am patiently waiting for your responses. Thank you!

We used H₂O₂ as Reducing agent for Permanganate or Manganese Dioxide in acidic conditions ( H₂SO₄) to get Mn 2+.

I have no idea if this also works for platinum. Check the redox potential values.
Also HCl can disturb and react to Chlorine.
Platinum is also catalyst and accelerate the decomposition of Peroxide.

I would use formaldehyde, ascorbic acid, dithionite or bisulfite.
