| Abstract: | Rapidly solidified Ni-50Al-5Si-2Fe-0.25Ce alloy was prepared and activated by leaching Al out.Its structure features and catalytic properties on fatty nitrile hydrogenation were investigated.It was found that the rapidly solidified precursor alloy was rich in Ni 2Al 3 and NiAl 3 phases;Compared to conventionally prepared Raney Ni,the new catalyst has small pore diameter,fine f.c.c. Ni grain,big lattice parameter,and high activities and selectivities on two selective reactions to primary amine as well as secondary amine. |
