Abstract

A Fe-Ni-P amorphous alloy catalytic reactor consists of a Fe-Ni-P amorphous alloy composite fiber and a catalytic reactor shelf. The length of the composite fiber is continuous, and the cross sectioncan be round, flat, and other shapes; the cross-sectional area of the composite fiber is not more than 2mm2; the coating layer is Fe-Ni-P amorphous alloy and thickness is not more than 0.5mm; the corewires of the composite fiber are polymer. The production method of the reactor comprises the following steps: (1) degreasing the polymer fiber with alkaline solution; (2) coarsening the fiber surfacewith chromic anhydride and sulfuric acid solution; (3) sensitizing the fiber with acidic tin salt solution;(4)activating the fiber surface with silver nitrate and aqueous ammonia solution; (5) electroless plating the fiber with Ni-P alloy; (6) electro brush-plating the fiber with Fe-Ni-P amorphous alloy; (7) preparing the Fe-Ni-P amorphous alloy catalytic reactor.

Description

technical field [0001] The invention relates to the field of amorphous alloy catalysts, in particular to an Fe-Ni-P amorphous alloy catalytic reactor and a production 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 alloy cataly...
