Structure and Energy Profile of the Skeletal Nickel SurfaceAccording to the Small-Angle X-Ray Diffraction and Adsorption CalorimetryData
2020
A systematic study of the surface of Raney nickel-based pyrophoric catalysts
by small-angle X-ray diffraction analysis was carried out for the first time.
The parameters of the crystallites constituting the active catalyst surface were
determined. A correlation between the surface structure and the activity of
skeletal nickel for the liquid-phase hydrogenation reactions was demonstrated.
The effect of treatment of Ni–Al alloy with sodium hydroxide and hydrogen
peroxide on the catalyst particle size and on the course of the hydrogenation
reaction was revealed and substantiated. The X-ray diffraction data on the
catalyst surface structure and the adsorption calorimetry data were correlated
with the skeletal nickel activity parameters.
