Production method of nickel-iron-phosphorus amorphous alloy catalytic reactor

Abstract

The invention provides a nickel-iron-phosphorus amorphous alloy composite fiber. The length of the composite fiber can be continuous, the cross section of the composite fiber can be circular, special-shaped and the like, the external diameter of the composite fiber is 0.01-0.2 millimeter, and the diameter of core yarn of the composite fiber is 0.005-0.08 millimeter; a coating layer of the composite fiber is nickel-iron-phosphorus amorphous alloy, the nickel-iron-phosphorus amorphous alloy is prepared from 40-85% of nickel, 10-20% of ferrum and 6-20% of phosphorus, and the core yarn of the composite fiber is made from a polymer. A preparation method of the composite fiber comprises the steps that (1) a polymer fiber is degreased; (2) the fiber surface is coarsened; (3) the fiber is sensitized; (4) the fiber surface is activated; (5) chemical nickel-iron-phosphorus plating is carried out on the fiber; (6) the nickel-iron-phosphorus amorphous alloy is plated on a fiber electric brush.

Description

technical field [0001] The invention relates to the field of catalyst production, in particular to a nickel-iron-phosphorus amorphous alloy catalytic reactor and a preparation method. Background technique [0002] Amorphous alloys have the following characteristics: ①Amorphous alloys can be made into samples of various compositions in a wide range, so that their electronic properties can be adjusted in a wide range; ②The catalytic active center can be a single The form is evenly distributed in a chemically uniform environment; ③The surface of the amorphous alloy has a high concentration of unsaturated centers, and the coordination number of the unsaturated centers has a certain range, so its catalytic activity and selectivity are generally better than those of the corresponding 4. The non-porosity of its surface is that it gets rid of the problem that the diffusion of reactive species in the presence of multiple catalysts affects the surface reaction. [0003] Amorphous all...

Problems solved by technology

The idea of ​​the liquid phase method is to melt the master alloy uniformly first, and then adopt the method of purification and rapid cooling to rapidly cool the alloy liquid in a short period of time. The main advantages of this type of method are that the preparation is simple and the cycle is short. The size is largely limited by the ability of the alloy to form amorphous
