Hydrothermal Synthesis - an overview | ScienceDirect Topics

Hydrothermal Synthesis. Hydrothermal synthesis is a very powerful tool for producing various functional nanomaterials of transition-metal compounds, such as oxides, hydroxides, and sulfides. In many cases, self-organized hierarchical nanostructures, such as nanoflowers and nanourchins, can be obtained spontaneously.
