Co-Fe-B amorphous alloy catalyst, its preparation method and application

Abstract

The invention discloses Co-Fe-B amorphous alloy catalyst and its preparation. The mole ratios of the components are: Co: 0-32%, Fe: 0.1-32%, B: 67-70%. The catalyst of the invention passes X-ray diffraction and selective-area electronic diffraction tests, and has apparent non-crystal structure and 19-71m2 / g surface area. The catalyst is utilized to acetonitrile election hydro-preparation of ethamine. The method has simple operation and the good catalyzing and active selection to the reactions of hydro-furfural, hydro-dextrose and cinnamaldehyde.

Description

technical field

[0001] The invention relates to a Co-Fe-B amorphous alloy catalyst and a preparation method thereof, in particular to a Co-Fe-B amorphous alloy catalyst used in the selective hydrogenation of liquid phase acetonitrile to prepare ethylamine Co-Fe-B amorphous alloy catalyst and a preparation method thereof. Background technique

[0002] Nano and amorphous alloys are the hotspots and frontiers of current catalysis research. Due to its unique structural characteristics of long-range disorder and short-range order, nano-amorphous alloys exhibit excellent catalytic activity, selectivity and resistance to sulfur poisoning in many hydrogenation reactions, and have become the most promising new materials in the 21st century. Generation Catalyst.

[0003] At present, the amorphous alloy catalysts that are widely used are mainly concentrated on binary amorphous alloy catalysts, such as Ni-B, Co-B, Fe-B, Ru-B and other catalysts. Miscellaneous other metals have also be...
