Problems solved by technology

[0003] Although our group has solved the problem of preparing solid-solution titanate materials in the patent "Titanium-Zirconium Solid Solution Micro / Nano Thin Film on Amorphous Metal Surface and Its Preparation Method" (application number: 201110153429.0), but because the prepared titanium-zirconium The solid solution micro / nano thin film is a film-like product, which has limitations and deficiencies such as limited photocatalytic activity, non-recyclable amorphous metal substrate, and a single substrate material for preparation. Difficulties such as complexity and difficulty in mass production, especially the inability to obtain completely single and pure powdered materials

In addition, during the transformation process, the microstructure and organization of the original film-like product will be destroyed, which will reduce the photocatalytic performance of the product and increase the preparation cost.

Therefore, there are problems in the preparation of solid-solution titanate powder in the prior art, such as limited types of raw materials and low utilization rate, low purity and low photocatalytic performance of the prepared materials, difficult separation methods, difficult mass production, and high cost.
