Nano tungsten trioxide hydrothermal method (Hydrothermal Method) is a synthetic method for preparing nano tungsten trioxide materials. It is carried out in a high-temperature and high-pressure aqueous solution environment by using a hydrothermal reaction.
In the hydrothermal method, an appropriate precursor material (usually a metal salt or a metal-organic complex) is usually dissolved in an aqueous solution to form a reaction solution. Then the reaction solution is placed in a high-pressure reactor, and the reaction is carried out at a certain temperature and pressure. Common reaction temperatures range from 100°C to 300°C, and pressures generally range from 1 to 10 MPa.
Under the conditions of high temperature and high pressure, the precursor substances in the solution react chemically to form nano-tungsten trioxide particles. By controlling parameters such as reaction temperature, reaction time, and reactant concentration, the size, morphology, and structure of nanoparticles can be regulated.
The hydrothermal method has some advantages, such as simplicity, mild reaction conditions, and high product purity. In addition, the hydrothermal method can also realize the preparation of single-phase nano-tungsten trioxide, and can obtain high-quality nanomaterials in a relatively short period of time.
It should be noted that the hydrothermal method needs to pay attention to the safety of high temperature and high pressure, and follow the relevant specifications and guidelines of laboratories and chemical handling.
