摘要：

The ability of a benchtop powder X-ray diffractometer with a solid state detector to observe the ambient oxidation of ultrasmall (sub 2.5 nm) Pt particles, previously seen only with synchrotron XRD, is demonstrated. The oxidation is corroborated with STEM imaging and fast Fourier transform analysis.
