“…These all match well with observations of turbostratic α-Ni(OH) 2 . ,− The Fe catalyst showed reflections at similar positions, 14°, 20°, 36°, and 60° 2θ, however with lower intensity, which have been reported for highly distorted FeOOH structures. − The d -spacings were found between ∼6–8 Å obtained from the (0 0 3) reflection, with small variations as a function of Fe-content. Changes in turbostratic oxyhydroxide structures are difficult to accurately interpret due to c -axis stacking faults. ,,,,− The relative peak intensities of the (1 0 1) and (1 1 0) reflections continued to decrease at increased Fe content, which is consistent with formation of more distorted phase, in line with earlier observations of the effect of Fe intrusion in Ni lattices. , …”
