“… [19] between 115 and 220 µmol.g −1 for basic Ni-Mg-Al oxides with different compositions, by Rien J. et al. [20] which were between 89 and 133 µmol.g −1 for Ni oxides derived from hydrotalcites, or significantly lower than those reported by Li Y. et al [21] between 290 and 790 µmol.g −1 for Ni-supported on natural palygorskite-clay.…”
