Chris Kliewer, together with Timothy Livingston Large and Brian Patterson, published a paper in “The Journal of Physical Chemistry C” on “Kinetics of the Formation of a High-Temperature Surface Oxide on Pt(111) under Near-Ambient Pressure O2”
In this work, the authors used near-ambient pressure X-ray photoelectron spectroscopy (NAP-XPS) to investigate the oxygen surface coverage on Pt(111) at temperatures from 873 to 1073 K in a 1 mbar O2 environment. They discovered and characterized the formation of a high-temperature stable surface oxide (PtOx) at temperatures substantially lower than previously known. Their results provide new insights into the mechanisms and kinetics of platinum oxide formation under these conditions and will be useful in understanding and controlling reactions on this important catalyst.
