Catalytic performance and dispersion Behavior of supported nano-amorphous alloy NiB/MCM-41 catalysts prepared by chemical reductive deposition

摘要

Supported nano-amorphous alloy NiB/MCM-41 catalysts were prepared by chemical reductive deposition. The as-prepared catalysts were characterized by XRD, SEM, TEM, EDAX, 1CP, and N-2 adsorption-desorption. The amorphous alloy structure of NiB active sites, mesoporous structure of catalysts, and higher BET area have been proved by the experiments. The catalysts have given excellent catalytic activity and selectivity in the production of 3-(N-benzyl)-amino-4methoxy- acetanilide from 3-amino-4-methoxy-acetanilide and benzaldehyde.
