Figure 5
S 2p SXPS spectra collected at hν = 380 eV from air-oxidized heterogeneous chalcopyrite with bornite. (a) Chalcopyrite phase (point 1 in Fig. 4e) and (b) bornite phase (point 2 in Fig. 4e). Plots also include deconvoluted peak components from the sulfur species contributing to the S 2p profile (only 2p3/2 spin orbit components displayed): red, bulk sulfide; blue, disulfide; purple, polysulfide; orange, energy-loss feature; green, sulfate. |
