Synergistic effects of the bimetallic Ni-Fe systems and their application in the reductive amination of polyether polyols
We report the synthesis of x Ni- y Fe/γ-Al 2 O 3 catalysts which were applied to the reductive amination of polypropylene glycol (PPG) for the preparation of polyether amine (PEA). The catalysts were characterized by N 2 -sorption, X-ray diffraction, H 2 -temperature programmed reduction, energy-dis...

-temperature programmed reduction, energy-dispersive X-ray spectroscopy, and X-ray photoelectron spectroscopy to reveal the synergistic effect of the bimetallic Ni-Fe-loaded catalysts. It was found that in the reductive amination of PPG to PEA, the conversion and product selectivity of the reaction were closely related to the types of active centers of the catalyst. In particular, the surface Ni
