Embodiment 1

[0030] This embodiment prepares Fe according to the following steps 84 Si 4 B 8 P 4 Amorphous alloy strip:

[0031] Step 1. Processing of raw materials

[0032] Get Fe, Si, Fe-20%P and B raw materials (the purity of Fe simple substance, Fe-20%P alloy raw material is 99.9wt.%, the purity of Si simple substance and B simple substance raw material is not less than 99.99wt.%), through Mechanical grinding, alkali cleaning, degreasing, pickling, remove oxides and grease substances on the surface, and ensure that there are no other impurities on the surface of raw materials.

[0033] Step 2, preparation of master alloy ingot

[0034] According to the nominal composition Fe 84 Si 4 B 8 P 4 , the processed raw materials are batched, and then melted in a vacuum arc melting furnace under the protection of high-purity argon. In order to ensure the uniform composition of the alloy, the master alloy is repeatedly smelted in the furnace for more than 4 times, and finally the master ...

The catalyst is a strip, the components of all elements according to atomic percent are Fe<100-x-y-z>Si<x>B<y>P , x is more than or equal to 0 and less than or equal to 20, y is more than or equal to 0 and less than or equal to 20, and z is more than or equal to 0 and less than or equal to 10. The Fe-Si-B-P series amorphous alloy strip provided by the invention shows excellent catalytic degradation performance and amorphous forming ability, is a good dye degradation catalyst, and has a wide commercial application prospect.

Description

technical field [0001] The invention belongs to the application field of amorphous alloy strips and dye catalytic degradation thereof, and in particular relates to an Fe-Si-B-P series amorphous alloy catalyst for efficiently degrading dyes and a preparation method thereof. Background technique [0002] Due to its short-range order and long-range disordered atomic structure, amorphous alloys have many excellent properties, such as high strength, high corrosion resistance, and some unique performance functions. attention. Among many amorphous alloy systems, Fe-based amorphous alloys have attracted great attention in the field of applied research due to their excellent performance and low cost. [0003] In recent years, with the development of the chemical industry, synthetic dyes have been widely used, but while providing colorful colors to the world, it also makes dye wastewater treatment a difficult problem. Dye wastewater is toxic and carcinogenic, and if it is discharged...
