The procedure involves first preparing a platinum nitrate which is then heated to expel nitrogen oxides. [3] H 2 PtCl 6 + 6 NaNO 3 → Pt(NO 3) 4 + 6 NaCl (aq) + 2 HNO 3 Pt(NO 3) 4 → PtO 2 + 4 NO 2 + O 2. The resulting brown cake is washed with water to free it from nitrates. The catalyst can either be used as is or dried and stored in a ...

Ammonium hexachloroplatinate is used in platinum plating. Heating (NH 4) 2 [PtCl 6] under a stream of hydrogen at 200 °C produces platinum sponge. Treating this with chlorine gives H 2 [PtCl 6]. [2] Ammonium hexachloroplatinate decomposes to yield platinum sponge when heated to high temperatures: [2] [5] 3(NH 4) 2 PtCl 6 → 3Pt(s) + 2NH 4 Cl ...
An aqueous solution of rhodium chloride, chloroplatinic acid, and sodium nitrate is evaporated and then fused in a porcelain dish between 460-480°C until the oxides of nitrogen cease (≈10 minutes).
