摘要： The present invention relates to a method for preparing nano ZrO2/HfO2 and metal nanoparticles. Firstly, an initial alloy mainly composed of Zr/Hf and Al/Zn is prepared using metal raw materials; Dissolve the initial alloy in a hot alkaline solution to obtain an intermediate solution; Then reduce the alkaline concentration or (and) temperature of the intermediate solution to allow the solid flocculent products containing Zr/Hf to precipitate from the intermediate solution after the concentration or (and) temperature is reduced, resulting in low crystalline nano ZrO2/HfO2; By further heat treatment, crystalline nano ZrO2/HfO2 was obtained. When precious metal elements are dissolved in the initial alloy, this method can also be used to prepare metal nanoparticle doped nano ZrO2/HfO2; After removing the nano ZrO2/HfO2 from the composite product, metal nanoparticles were further prepared.

摘要： The present invention relates to a method for preparing a nano-titanate, a nano-titanic acid and a nano-TiO2 containing doping E or embedding E nanoparticles, and the use thereof. By using an E-doped Ti-T intermetallic compound as a titanium source, and reacting it with alkaline solution at atmospheric pressure and near its boiling-point temperature, an E-doped titanate nanofilm is prepared with high efficiency and in a short time. Through acid treatment and (or) heat treatment, a titanate nanofilm containing embedding E nanoparticles, an E-doped titanic acid nanofilm, and a titanic acid nanofilm and a TiO2 flake powder containing embedding E nanoparticles can be further prepared.

摘要： A preparation method for nano titanate, nano titanic acid, and nano TiO2. A Ti—T intermetallic compound, as a titanium source, is reacted with an alkaline solution under ambient pressure at a temperature near the boiling point of the alkaline solution, enabling the efficient preparation of titanate nanofilm materials under normal pressure. On this basis, it is possible to economically produce titanic acid nanofilm materials and TiO2 nanosheet/powder. In combination with subsequent high-temperature and high-pressure reaction, titanate nanotubes, titanic acid nanotubes, and TiO2 nanotubes/rods can be efficiently prepared. The preparation method provided herein has simple operation and low cost, and can prepare various nano titanate, nano titanic acid and nano titanium dioxide materials, including nanofilms and nanotubes/rods, exhibiting good application prospects in the fields of polymer-based nanocomposite materials, ceramic materials, photocatalytic materials, hydrolysis-based hydrogen production, hydrophobic materials, sewage degradation materials, bactericidal coatings, anti-corrosion paints, and marine paints.

摘要： The present disclosure relates to a method for preparing a category of alloy powder and an application thereof. By selecting a suitable alloy system and melting initial alloy melt through low-purity raw materials, high-purity alloy powder, and matrix phase wrapping high-purity alloy powder are precipitated during the solidification process of the initial alloy melt, and the solid solution alloying of the high-purity alloy powder is achieved at the same time. Alloy powder can be obtained by removing the matrix phase wrapping the high-purity alloy powder; high-purity alloy powder can also be obtained by removing the matrix phase wrapping the high-purity alloy powder at an appropriate time. The method is simple and can prepare a variety of alloy powder materials with different morphology at nano-scale, sub-micron level, micron level, and even millimeter level.
