Adams' catalyst, also known as platinum dioxide, is usually represented as platinum (IV) oxide hydrate, PtO 2 •H 2 O. It is a catalyst for hydrogenation and hydrogenolysis in organic synthesis. [1] . This dark brown powder is commercially available.

2025年3月21日 · Platinum dioxide, also known as Adams catalyst, is a dark brown powder, a hydrated form of platinum (IV) oxide (PtO2), produced by heating chloroplatinic acid (H2PtCl6) with sodium nitrate (NaNO3). Platinum nitrate is produced, and this decomposes to Platinum (IV) oxide with evolution of NO2 and oxygen.
