Table 1. Platinum 4f7/2 values.

Note the Pt metal peaks need to be fit with an asymmetric peak-shape (in CasaXPS we use LA(1.2,85,70).  A CasaXPS ready file of sputter cleaned Pt metal can be downloaded here. This file also contains the valence band spectrum for Pt metal.  Pt 4f7/2 - 4f5/2 splitting is 3.33 eV.
