Figure 3. Normalized Ni K-edge XANES spectra of the as-prepared and used Ni5Ga3-a catalysts: (a) Ni5Ga3-400, (b) Ni5Ga3-500, (c) Ni5Ga3- 600, and (d) Ni5Ga3-700 (The used catalysts were collected after the 3 h CO2 hydrogenation at 300 °C.)
Figure 4. Normalized Ga K-edge XANES spectra of the as-prepared and used Ni5Ga3-a catalysts: (a) Ni5Ga3-400, (b) Ni5Ga3-500, (c) Ni5Ga3-600, and (d) Ni5Ga3-700 (The used catalysts were collected after the 3 h CO2 hydrogenation at 300 °C.)
Figure 6. Normalized XANES spectra of the fresh and used Ni5Ga3-500 catalysts: (a) Ni K-edge, (b) Ga K-edge. (Used catalysts were collected after 100 h ToS evaluation at 220, 260, and 300 °C, respectively.)
