“…4a the prole of the Ni8 sample was shown as an example). A similar behavior was previously observed by Li and coworkers 50 and by Guil-López and coworkers, 51 15 and/or small sizes of NiO would be conducive to this process, since there are more atoms at the interface promoting the solid-solid reaction. 52 To study the role of the amount of Ni and the oxide matrix on the reduction/oxidation behavior, TPR/TPO/TPR proles of high-loaded Ni/Al catalysts obtained from silicates and carbonates (Ni68 and Ni68-CO 3 ), previously characterized by XRD, were investigated (Fig.…”

“…It is clear that after calcination the structure of the Ni‐HT catalyst shows a layered ribbon structure . Moreover, the STEM image reveals a highly porous catalyst material and it seems that the porosity has an ordered structure.…”

“…Moreover, the STEM image reveals a highly porous catalyst material and it seems that the porosity has an ordered structure. The dual pore size distribution with average pore size about 3.5 and 18 nm was confirmed by detailed TEM analysis and N 2 physisorption . In an earlier publication, tomographic reconstruction showed that the pores have a rectangular morphology and regular distribution within the plates …”

“…Nanoconfinement of Ni particles by self-assembly of Ni atoms inside the nanoribbons of hydrotalcite-derived mixed oxide provided increased catalytic stability for methane steam reforming, compared to Ni supported on commercial support surface. [59] Metal embedment has also proven to be an efficient stabilization method for lactic acid production from glycerol. Morales et al showed that MFI constituted a stabilizing matrix for Sn and significantly decreased leaching of said Sn while slowing down deactivation in comparison to bifunctional carbon-silica composites and BEA zeolites.…”
