Platinum
Platinum X-ray photoelectron spectra, platinum electron configuration, and other elemental information.
Platinum • Transition Metal
Primary XPS region: Pt4f
Overlapping regions: Al2p
Binding energies of common chemical states:
| Chemical state | Binding energy Pt4f7/2 |
|---|---|
| Pt metal | 71.0 eV |
| PtO | 72.4 eV |
| PtO2 | 74.9 eV |
Interpretation of XPS spectra
- Pt4f region has well separated spin-orbit components (Δmetal=3.35eV).
- Peaks in the Pt4f region have an asymmetric peak shape for platinum metal.
- Platinum compounds, such as the oxide, have symmetric Pt4f peaks.

Discovered by J. Scaliger in 1735, platinum is a beautiful, gray-white metal that is malleable in its pure form. It is extremely resistant to corrosion and tarnishing, and will not oxidize in air, even at high temperatures. Platinum is very rare, and is naturally found as the uncombined metal. Because of its extreme durability and resistance to tarnishing, platinum is widely used to make jewelry. It is also used to make surgical tools, liquid crystal displays, and electrical resistance wires. Platinum is named for the Spanish word “platina,” meaning “little silver.”
