A kind of high (001) surface flaky zirconia and its preparation method

Abstract

The present invention provides a preparation method of high (001) plane flaky zirconia, which is prepared through hydrolysis and self-reaction of a single reagent of fluozirconic acid. According to the present invention, only two reagents, fluozirconic acid and ethanol, are used in the whole process, 5 synthetic raw materials are simple and easily available, reaction time is extremely short, and reaction temperature is low, thereby avoiding complicated procedures of reaction, calcination, cleaning and the like, and simplifying the process; and synthesized flaky zirconia particles are uniform, intact in crystal plane, high in (001) plane proportion and high in specific surface area, and thus have good application prospects such as adsorption, catalysis and sensing.

Description

technical field

[0001] The invention relates to the technical field of nanometer multifunctional materials, in particular to a high (001) surface flaky zirconia and a preparation method thereof. Background technique

[0002] Zirconia (ZrO 2 ) is a very important structural and functional material with excellent physical and chemical properties, such as high melting point (up to 2700 °C), high boiling point, high hardness, small thermal conductivity, large thermal expansion coefficient and good particle electrical conductivity Rate, and wear resistance, high temperature resistance, corrosion resistance and oxidation resistance. Since the 1980s, in addition to being used as a traditional refractory material and ceramic glaze, zirconia has also received more and more attention in the application of energy, environment and materials. The nano-micron zirconia is different from conventional materials in terms of optics, mechanics, thermodynamics and electromagnetics due to its t...
