Figure 1. (a) Schematic illustration for the preparation of FePt QDs/Ni-MOL; (b) PXRD patterns for samples and high-resolution XPS spectra of (c) Pt 4f, Ni 3p (Purple and Pink for Pt 4f5/2, Green and Yellow for Pt 4f7/2), and (d) Ni 2p for as-synthesized materials; (e) Pt L3-edge XANES spectra and (f) the corresponding k3-weighted FT spectra at R space for the FePt-5/Ni-MOL; and (g) the corresponding R-space fitting curve for the FePt-5/Ni-MOL.
Figure 6. In situ XPS spectra of (a) Fe 2p (purple for Fe 2p1/2, pink for Fe 2p3/2), (b) Pt 4f and Ni 3p (purple and pink for Pt 4f5/2, green and yellow for Pt 4f7/2, blue for Ni 3p) of FePt-5/Ni-MOL, and (c) Fe 2p, (d) Pt 4f, and Ni 3p of activated FePt-5/Ni-MOL; (e) Pt L3-edge XANES spectra and (f) the corresponding k3-weighted FT spectra at R space for the FePt-5/Ni-MOL before and after photocatalytic cycling tests; and (g) schematic illustration of the photocatalytic H2 evolution mechanism for FePt-5/Ni-MOL.
