AI Technical Summary

Problems solved by technology

[0003] Semiconductor materials such as silicon dioxide are widely used in the field of photocatalysis due to their high specific surface area, high mechanical strength, and low price, but their catalytic efficiency is low, and the utilization rate of solar energy is low. Easy to aggregate and loss
The synergistic effect of the coating material and the noble metal enhances the activity of the catalyst in the chemical process, but the thickness of the coating is only between 0.2nm-2nm for each layer. Agglomeration is easy to occur, which makes it difficult to control the use of precious metals and cause waste

Abstract

The present invention first prepares Fe, TI, AL, Zr, Mg alloy products by ordinary casting forming technology, the cost is low and the performance is stable, and then the Cu, Pt and Ag dissolved in the organic solution are sprayed on the surface of the product for catalysis by an electronic spray gun. Then use pulse technology to fuse it with the product, combine solid-state diffusion connection and instantaneous liquid phase connection technology, reduce the amount of precious metals, and make the alloy material have a photosensitive catalytic function, the precious metal is not easy to escape from the alloy material, and the composition is stable. Long service life, energy saving and environmental protection, can be used to prepare photosensitive catalytic devices such as air purifiers, containers of photosensitive catalysts or heaters with photosensitive catalytic functions.

Description

technical field [0001] The invention relates to the field of metal material preparation, in particular to a photosensitive catalyzed energy-saving alloy material. Background technique [0002] Photocatalytic materials do not react chemically by themselves. When light hits its surface, they are excited to generate electrons and holes. These electrons and holes are excited to the surface of photoactivated materials, so that the surrounding oxygen and water molecules are excited to form Negative ions with extremely strong oxidizing ability, so as to effectively degrade toxic and harmful gases and organic substances around. [0003] Semiconductor materials such as silicon dioxide are widely used in the field of photocatalysis due to their high specific surface area, high mechanical strength, and low price, but their catalytic efficiency is low, and the utilization rate of solar energy is low. Easy to reunite and loss. [0004] Noble metals (such as copper, silver, gold, platin...
