Temperature programmed XANES at the Ni K-edge during the in situ reduction of four different preparations of Ni/γ-Al2O3. The calcination conditions were 673 K for 8 h in nitrogen, 773 K for 8 h in nitrogen, 673 K for 8 h in 5% steam in air, and 773 K for 8 h in 5% steam in air. The ramp rate was 5 K min−1 from room temperature (highest intensity of the white line at 8353.0 eV) to 923 K (lowest intensity of the white line).
