Hydrothermal Synthesis - an overview

Hydrothermal Synthesis - an overview

Hydrothermal synthesis refers to material synthesis by chemical reaction performed within a sealed vessel filled with aqueous of reagents under temperatures above 100°C and autogenously high pressure. Different from the sol-gel and the coprecipitation methods (which will be described in S2.4), hydrothermal synthesis is usually carried out within specialized reaction vessels …

Hydrothermal Synthesis - an overview

Hydrothermal synthesis is defined as a method to prepare inorganic materials in aqueous solutions above ambient pressure and temperature [73,74]. Solvothermal term is applied for the reactions performed in organic solvents. Usually, the reaction is carried out in sealed reaction vessels defined as autoclaves.

Hydrothermal Processing - an overview

The mechanochemical–hydrothermal synthesis utilizes aqueous solution as a reaction medium. Mechanochemical activation of slurries can generate local zones of high temperatures (up to 450–700°C) and high pressures due to friction effects and adiabatic heating of gas bubbles (if present in the slurry), while the bulk system is close to room temperature [400] .

As described earlier, continuous hydrothermal synthesis is probably the most effective method for the scale-up approach. However, an additional process in this method is necessary for surface modification. Figure 24.9 shows the scheme of the ideal scale-up process to prepare surface-modified iron oxide nanoparticles. In this system, aqueous metal salts and organic surfactants …
