Reduction Kinetics of the Nanocluster [HxPMo12O40⊂H4Mo72Fe30(O2CMe)15O254(H2O)98-y(EtOH)y]

“…The bands are associated with the nucleus shell charge transfer between Keggin guest and host (550 nm) and the [Mo(V) ? Mo(VI)] charge transfer in the Keggin cluster (880 and 1045 nm) [29]. The FT-IR and Raman spectra of the synthesized product (Figs.…”

“…The FT-IR and Raman spectra of the synthesized product (Figs. 3 and 4, respectively) show the characteristic features of FeMoC (Tables 1 and 2, respectively) [28][29][30][31]. The FT-IR peaks at 1267, 2921, and 2971 cm -1 (Fig.…”

“…Figure 1 shows a typical TEM image, which reveals spherical nanoparticles of ca. 2.5 nm in diameter characteristic of FeMoC [29]. The UV-visible spectrum of the as prepared material is shown in Fig.…”

“…The UV-visible spectrum of the as prepared material is shown in Fig. 2, and shows bands at 548, 880, and 1045 nm corresponding to the characteristic features of FeMoC [25,28,29]. The bands are associated with the nucleus shell charge transfer between Keggin guest and host (550 nm) and the [Mo(V) ?…”

“…All characterization techniques show the materials to be identical to previously reported FeMoC samples [25,[28][29][30][31]. TEM was performed using a JEOL 1230 high contrast transmission electron microscope at 120 kV equipped with a CCD camera.…”
